Eris Essay

Saturn has an average radius of nine times that of Earth, it is the second largest planet after Jupiter and sixth from the sun.

Uranus is the only giant planet whose equator is nearly at right angles to its orbit and has 5 large moons and 22 smaller moons. It is, also, the only planet in our solar system to spin on its side. Uranus

During the first millennium B.C. scientists realized that astronomy had to become more scientific. Middle Eastern and Chinese cultures started studying the Sun, stars and the planets more closely in an attempt to learn more about our position in the universe.. Star positions also became important tools in understanding directions, and helping with navigation. One philosopher stated in 434 B.C. that the Sun was a ball of fire 60 kilometres in diameter, hovering 6500 kilometres above Earth’s surface. Around 130 B.C., Ptolemy wrote Almagest, which was a huge collection of astronomical data which included mathematical models, information about eclipses, and planetary and stellar positions and movements. It remained a major go to book for astronomy for hundreds of years, and was not seriously challenged until Copernicus disputed the geocentric model of the solar system in the 1500’s

What will happen to eris in the future?Eris is the largest dwarf planet in the solar system, and the ninth planet orbiting the sun. Eris’s nickname is Xena.It was located behind the keisllist belt.There is only one moon surrounding Eris.

Pluto, a dwarf planet, and Uranus, a planet, take turns being the most distant of the major bodies of our solar system in reference to the Sun For years, scientists were under the mistaken hypothesis that Pluto was the most distant. Scientists, in an attempt to study astronomical data, learned their hypothesis was inaccurate. Fortunately, it is of the scientists nature to investigate all data. On the basis of the data, the astronomers learned of the fact Uranus and Pluto have intersecting orbits. In addition, during the course of their investigation, they learned much of the nature of Uranus and Pluto.

The Moon is Earth’s moon, which is about 240,000 miles away. A moon is a satellite that revolves around a planet.

what is the second largest moon in the Jovian System is Jupiter’s moon, Callisto! It was discovered in 1610 by Galileo Galilei. It orbits beyond Jupiter’s radiation belts.

much bigger. Its sheer size in relation to the nine known planets means that it can only be

Which is the largest of all dwarf planets? Pluto is a dwarf planet in our solar system and has been given the nickname Xena. Pluto was once considered the ninth main planet from the Sun. Scientists discovered Pluto on February 18, 1930 (history.com). Several objects surround Pluto including Nix (Pluto’s natural satellite) and Hydra (Pluto's outermost satellite) , comets, and the constellations “Teapot”, and “Scorpius”. Pluto is a fascinating planet because of its discoveries and missions, composition, and research.

Scientists of the New Horizons mission have found Pluto to be 1,473 miles in diameter, which is larger than many prior estimates. Pluto’s size means that its density is slightly lower and the fraction of ice in its interior is slightly higher. Also, the lowest layer of Pluto’s atmosphere is shallower. They were able to confirm that Pluto’s largest moon, Cheron is 751 miles across as well as the smaller moons Nix is estimated to be about 20 miles across, while Hydra is roughly 30 miles across. Pluto’s even smaller moons, Kerberos and Styx will be determined in later months when the data is transferred to

As of 2006 dwarf planet was a new category and a new thing for astronomers. By definition it is simply just a planet except that it cannot complete a neighbourhood orbit around the sun. After planets were put into this grouping was noticed that all of these planets were much smaller in size and significantly farther away from the sun and the rest of the planets. All of the dwarf planets still orbit the sun however; it is just at a further distance.

The other 22 are further away and some are smaller than Pluto. One of the largest moons is Titania and is covered with small craters. The second largest moon is Arial, it has craters, valleys and canyons on it. The darkest moon orbiting Uranus is Umbriel.

Did you know that Eris is colder than Neptune? Eris is the furthest dwarf planet from the sun, and is also the most massive of the currently recognized dwarf plants. Planet Eris extends far beyond the Kuiper Belt, a zone of icy debris beyond the orbit of Neptune. Eris is so far from the sun that its atmosphere sometimes freezes due to lack of sunlight. Over the course of the hundreds of years it takes the Eris to orbit the Sun, it thaws as it gets closer to the Sun’s heat.

our solar system, but they are unimportant compared to the nine major planets. In this paper I will discuss the planets and how they are each unique.

Since ancient times, the universe had captivated people’s imagination and curiosity. With the limitation on technology, early sky watchers were only capable of classifying objects they observed as either a star or a planet. During the twentieth century, with advancement in telescopes to see further into space with more accurate details, scientists were able to find numerous stars and planet like objects within the solar system. Scientists had no trouble classifying objects such as Uranus and Neptune as planets. However, the real trouble came when they discovered a planetary object called Ceres. Objects like Ceres and Pluto behaved similarly to regular planets. Because of the limitations on the technology at the time, it was very difficult
