Dwarf planet

Dwarf planets are considered to be those mass’s in space which are neither planet nor natural satellite. More explicitly, they are a mass which, unlike a moon, orbit around the sun, and due to the pull and force of their self-gravity are of a sufficient mass that they form an almost rounded spherical shape however they are not of a sufficient size to gravitationally clear the neighbourhood around their orbit. (Williams, M) In comparison the definition of a planet, as defined by the…

newest and smallest known planet in our solar system. Pluto, for 75 years would be thought of as the ninth planet in our solar system. It wasn’t until the discovery of Eris in 2005 that astronomers began to question what defines a planet. After the discovery of Eris and other celestial objects such as MakeMake, Pluto along these new discoveries have been defined as dwarf planets. They are categorized as dwarf planets because they are smaller compared to the other planets and with their size, are…

Today 10 years after the tragic event people who were affected were able to rebuild their lives and let everything return to normal. On August 24th, 2006 the planet Pluto was officially downgraded to a dwarf planet. There are many reasons the planet was demoted, for instance, Pluto meets all the criteria for being a full sized planet but one, the 3rd requirement states the…

such as new galaxies, planets believed to have atmospheres with the possibilities of life, or even dwarf planets being discovered every day. I chose to write about the dwarf planet Ceres, according to Elizabeth Howell, (Space.com Contributor), “it was first discovered by Sicilian astronomer Giuseppe Piazzi on Jan. 1, 1801, in the asteroid belt between Mars and Jupiter, the closest dwarf planet to Earth.” [1] I took a huge interest in finding out more about this dwarf planet because the whole…

the solar system’s beginning. Its existence debunks the original theory of the belt’s formation, consequently given way to the conjecture predicting a shuffling of the planets resulting in their current placement. Gravitational fields of Kuiper Belt Objects, or KBOs, have given evidence as to the existence of another undiscovered planet- dubbed…

stars, explore planets and other solar systems. There's just something extravagant about it, nevertheless it can also be dangerous and can kill you if you're not prepared just think of the climate on other planets.We also produce lots of litter when leaving earth's atmosphere but we could find cleaner fuels. We should not colonize space it is dangerous and could harm other planets, but we should be able to explore it with cleaner fuels. Nevertheless mars, “This strange earth like planet does…

What is the moon? How was it made? The moon is a large celestial object that is orbiting around the Earth. It takes around 23.7 days to rotate around the Earth fully. The moon's gravitational pull can be so strong it is able to control the tides in the ocean. There's many theories about how the moon was formed. For example, one of the ways scientists feel like the moon was made is that a mars like object collided with earth. While earth was still forming a big chunk of it came off and was…

Major exploration; is it worth the risk? “There are billions of places out there that we know nothing about. The fact that we know nothing about them excites me, and I want to go out and find them. ” This quote was spoken by Brian Cox when Cox spoke this saying, it was a call to action to explore. When I read the multiple informational texts in collection 4, I learned that space and ocean exploration has brought many medical and technological advances. Although there is some risk with…

can sustain. The World Wildlife Fund estimates by 2030 we will be consuming two planets' worth of natural resources. (Austen) At this rate, in the nearby future, we will run out of resources and energy, however, through space travel, we can get these resources back. For instance, the moons of Jupiter, Saturn, Uranus and Neptune contain high quantities of water, carbon and nitrogen. (Austen) These are simply a few planets high in resources. Another major issue currently facing civilization is…

bodies from forming in the gap between Mars and Jupiter, causing the small objects that were there to collide with each other and fragment into the asteroids seen today (Space.com). In the 1800's, Giuseppe Piazzi discovered what he thought to be a new planet. He named the asteroid Ceres and by the 19th century, there were several smaller bodies found and that were named; including Pallas, Vesta, and Juno.…
