Dwarf planet

and its five moons. It has a secondary mission and that is to explore the Kuiper Belt. Pluto is probably the “planet” we know the least about, at least before the New Horizons space probe passed it a few months back. First discovered in 1930 by an astronomer named Clyde Tombaugh, Pluto was considered the ninth planet in our Solar system for over 70 years. Then in 2003, Eris, a small planet larger than Pluto,…

Introduction An extrasolar planet also known as exoplanet is any planet that orbits a star not within our solar system. The first real discovery of an exoplanet was made in 1995 by the Swiss team of Michel Mayor and Didier Queloz of Geneva. The planet that they discovered was at least half the mass of Jupiter and smaller in size. NASA has confirmed 1746 exoplanets exist and there is surely more to be discovered. The Kepler mission was too find and statistically characterizes planets outside of…

universe. Much of the research relates to investigations in the laboratory relating to synthetic biology and how it can lead to better understanding of alien life in other planets outside the solar system. The most interesting idea is Sasselov’s claim that super-earths have better chances of harboring life than earth-sized planets. Personally, I have been interested in studies that relate to investigations about alien life. Sasselov writes that lab tests here on earth could provide important…

the planets, moons, stars, comets, etc. The major difference found between Muggle astronomy and Wizarding astronomy is that the Muggle world has "laws" that explain what they see in the universe. The study of these laws of the universe in the Muggle world is called "physics". Although these laws do explain a vast majority of what the Muggles see on Earth and in the universe, it may not hold true in the Wizarding world. Section B Mercury Mercury lacks an atmosphere. As a result, the planet…

Aaminah Azhar Astrobiology Spring 2015 Test 1 1. Name and describe five important steps in the formation of planets based on our current scientific understanding. a) Star and planet formation starts inside a collapsing cloud of gas and dust inside a bigger cloud called a nebula. Because of gravity pulling materials in the collapsing cloud closer together, the center of the cloud gets increasingly more compressed and because of this get hotter. The dense hot core of this collapsing cloud becomes…

Once the smallest member of the planetary system and now merely a “dwarf planet”, Pluto’s story has always fascinated people of the Earth. The tiny planet always manages to intrigue scientists and if the latest report is anything to go by, one can only say that Pluto is peculiar to the core. Scientists are saying that the planet may have hosted liquids on its surface within the last million years. The fact was stated in a report which was tabled at the Lunar and Planetary Science Conference on…

Pluto, the most puzzling world in the solar system, is the second largest dwarf planet made of ice and rock. It is 5.9 billion km from the Sun; it has the width of North America. It is a very cold place with minimum temperature of -370 degree Fahrenheit on the surface. One year on Pluto is equal to 248 Earth’s years; it takes a very long time to orbit the Sun. In addition, a day in Pluto lasts 6 Earth’s day. Pluto is a world that stands with light and shade, what causes this contrast may be that…

formed. • Gas and dust form in a size 10 times our solar system. 4. What creates a star’s heat/energy (use the words hydrogen and helium in your answer). • Burning hydrogen and converting it into helium. 5. What's the most common type of star? • Red Dwarfs. 6. Why do bigger stars die faster than smaller stars? • Burn fuel more quickly, because they contain more mass. 7. How old is our sun? • 4.5 billion years. 8. When will our sun die? • When the sun is out of fuel; in 5 billion years.…

in the Muggle world. It not only helps the understanding of the constellations and planets, is the source where students do their magic powers stronger. This year, we have studied our Solar System and its planets. Next, we will list the planets of our Solar System and examples of its facts: Mercury: its period is only 59 days, exactly two thirds part of its orbital period. Its a rocky…
