As many of us know, NASA is consistently making new discoveries. The newest discovery has me quite intrigued. The findings that imply that the planet, Ceres, has a weak interior. This is evaluated by monitoring the variations in Ceres’ gravity fluctuations, even though they are subtle it is enough of a clue to determine the internal structure. This new data proposes that Ceres has a weak interior, and water and light particles of unknown material separated from rock in the early years during a heating phase.
Ceres, is the largest object in the asteroid belt between Mars and Jupiter. It is approximately 587 miles in diameter, this also makes it the largest of the minor planets within the orbit of Neptune. This planet is composed of rock and ice; Ceres is estimated to take up at least one third of the mass of the entire asteroid belt. Its round shape is contributing to the weak interior and gravity. The magnitude of Ceres from Earth ranges from 6.7 to 9.3 explaining why it is too dim to see with the naked eye.
The dwarf planet Ceres, which is larger yet less dense, is believed to have a large amount of ice and may even have subsurface liquid water. Ceres was the first dwarf planet discovered by the spacecraft Dawn whom is now studying it in great detail. Scientists with NASA’s Dawn mission have identified with multiple photos that

Ceres is much less dense than Earth, the moon, and many other rocky bodies within the solar system. It has been suspected that Cere’s contained low density materials such as water ice, which has been shown to rise to the outer layer along with other light material. This division of layers is less pronounced inside Ceres than the moon or many other planets in our Solar System, which is what separates these other structures from planets like Earth, which is made up of a metallic core, semi fluid mantle, and outer
Ultimately the development of previous inferences and observations which have developed our current model for the Earth’s composition and interior structure are a key concept in understanding our future developments towards resourcing our planet and understanding how it works to a further degree.
It was at first thought to be bigger than Pluto later it ended up being somewhat smaller than Pluto. Eris finishes one rotation around the Sun in 580 years. Eris is the reason why Pluto’s planetary status was changed to being a dwarf planet. The Kuiper Belt has a section called Classic Kuiper Belt. This is the busiest area of this belt and is situated at a distance of around 42 to 48 AU. In the beginning, when the solar system was created gas, dust and rocks, came together to form planets. Most of the debris was swept away by gravitational pull for those planets, but some debris survived because they were far enough away to not be affected by the gravitational pull for those planets. Finding the Kuiper Belt gave us more insight into the mystery of the objects located in the Kuiper belt. Most KBO’s are so far away that their measurements cannot be concretely calculated. By using the data collected by the Spitzer space Telescope most of the KBO’s have known sizes. In 2015 the New Horizon Spacecraft flew past Pluto for an up close exploration of the Kuiper Belt Objects. The primary real expectation of the Kuiper belt's presence, most planetary researchers now agree, originated from Uruguayan cosmologist Julio
While studying the solar system in our eighth grade science class, we were each assigned a constellation to research. The constellation that was assigned to me was Cepheus. In this paper my goal is to explain the myth behind this constellation and describe its features.

Although Pluto was discovered in 1930, limited information on the distant planet delayed a realistic understanding of its characteristics. Today Pluto remains the only planet that has not been visited by a spacecraft, yet an increasing amount of information is unfolding about this peculiar planet. The uniqueness of Pluto's orbit, rotational relationship with its satellite, spin axis, and light variations all give the planet a certain appeal.
This liquid water, in combination with a rocky silicate sea floor and radiolytically produce surface oxidants, may provide for a chemically rich ocean that would be considered habitable. While the surface of Europa may contain clues about the composition of an interior ocean, debate still continues about the surface’s chemistry and how exogenous radiation processing and endogenous oceanic emplacement play a role on this moon. One way of understanding Europa is determining if the external composition reflects the internal ocean chemistry. Results from the NIMS (Near Infrared Mapping Spectrograph) instrument on Galileo inferred that the surface of Europa was dominated by hydrated sulfate salts that would be probable in evaporates from an internal ocean. In finding that these spectral signatures are more predominant in what seems to be younger terrains, it strengthens the hypothesis that these are more newly sited evaporates. Further Study of the spectra, however, showed that these same NIMS surface spectra could be explained just as well by a surface dominated by hydrated sulfuric acid. Sulfuric acid is a probable outcome of bombardment of a frozen surface by sulfur ions. These sulfur ions are ultimately come from volcanoes located on Io, and then dissociated, ionized, and accelerated by Jupiter’s quickly spinning magnetic field until they hit Europa. Such radiolysis could also clarify the sulfur dioxide and sulfur allotropes seen on the surface of Europa and their favored appearance on the more heavily bombarded trailing hemisphere. The existence of sulfuric acid and other sulfur products appears to be nearly unavoidable, but the salt hypothesis is still convincing (Brown 1).
2,870,990,000 km (19.218 AU) from the Sun, Uranus hangs on the wall of space as a mysterious blue green planet. With a mass of 8.683e25 kg and a diameter of 51,118 km at the equator, Uranus is the third largest planet in our solar system. It has been described as a planet that was slugged a few billion years ago by a large onrushing object, knocked down (never to get up), and now proceeds to roll around an 84-year orbit on its belly. As the strangest of the Jovian planets, the description is accurate. Uranus has a 17 hour and 14 minute day and takes 84 years to make its way about the sun with an axis tilted at around 90° with retrograde rotation. Stranger still is the fact that Uranus' axis is almost parallel to the ecliptic, hence the expression "on its belly".
Findings on Earth and other planets suggest extraterrestrial life could live in outer space, further encouraging scientists to proceed with their research. Discovering water is a great step for finding habitable planets. According to new studies, “Mars had a shallow pool of briny water on its surface long ago, NASA said in announcing what could be the strongest evidence yet that the now-dry Red Planet was once hospitable to life. ‘If we are correct in our interpretation, this was a habitable environment,’ Mr. Squyres said. These are the kinds of environments that are very suitable for life” (Bridges). Little evidence proves beings live on Mars now, but this dried up water source provides strong proof that Mars could have inhabited life in the past. Water is a key element of survival, and can also house marine life. Marine life could have simply died out when the water dried up. If Mars was truly inhabited by extraterrestrials long ago, then scientists cannot rule out living beings on any other planet in the universe, and must continue searching. Europa, one of Jupiter’s moons houses...
Right alongside the fifth and largest planet in our solar system, Jupiter, orbits a moon only about the same size as Earth’s moon. On this moon, is an icy surface that scientists are trying to uncover. Due to the presence of what they believe to be water, there is the possibility of life on this moon named Europa.
In Christine Evan’s play Trojan Barbie, a vacationing, English, doll repairing tourist by the name of Lotte is hastily taken hostage into the ancient world of Troy’s Trojan Women Camp, while on a singles-tour of modern day Troy. This piece, written in 2009 for Evans niece pays homage to the classical tale of Euripides Trojan Women, revived with a 21st century take on the current times less than fiction reality of warfare and sexual politics. However, Evans also assists in updating the foundation of the piece by introducing the character of Lotte into the scene. Though Lotte is on tour at the time she very much serves as a tour guide for the audience throughout the play. Although she may not be a major character such as a lead or a villain,

Asteroids can be found orbiting the Sun in a belt between Mars and Jupiter; this is called the Asteroid belt or Main belt. The asteroid belt has been said to probably contain millions of asteroids that are all different. There are more than 20,000 numbered asteroids. Some times asteroids get knocked off the asteroid belt. As asteroids revolve around the Sun in elliptical orbits, Jupiter’s gravity and getting to close to Mars or another asteroid can change an asteroids path, this could send an asteroid out of the asteroid belt and into space across the orbits of other planets. An example of asteroid orbits changing is Mar’s moons Phobos and Deimos. These were asteroids that went to close to Mars and got caught in its orbit.

Pluto is located 7.5 billion kilometers from Earth and is only over 2,000 km in diameter. Pluto has been labeled both a planet and a dwarf planet over the years. As said by USA Today, “a planet is a celestial body that: is in orbit around the sun, is round or nearly round, and has "cleared the neighborhood" around its orbit, meaning it is not surrounded by objects of similar size and characteristics.” Pluto only follows two of the three rules of a planet. Pluto crosses over Neptune’s orbit and is near other dwarf planets like it. Even though it breaks one rule it was officially named a dwarf planet in “August 2006”, as stated by the Library of Congress. After this event Pluto still only has one correct classification. Pluto is a planet because
The fourth planet from the sun is Mars. “Mars is named after a mythological figure-the Roman God of War. Due to Mars color it is also known as the red planet. Mercury is the tiniest planet then Mars. Scientist have found that mars has the largest mountain compared to the other planets. Furthermore, this mountain is named Olympus Mons, it is a shield volcano, it is 21 km high and 600 km in diameter. Scientist have discovered recent lava on the planet, therefore the volcano may still be active.
