Inner and Outer Planets Have you ever wondered the differences between the planets while looking up at the night sky? Although the planets have many differences, we can still tell them apart from what we’ve learned from them. They have some similarities, not much, but it’s enough for us to be able to compare them. We’ve learned their sizes, layers, what they’re made of, how they were founded and much more. Unlike the outer planets, the inner planets have rocky surfaces, which is called the…

colossal. Billions of galaxies among galaxies, each of them possibly containing planets and worlds of their own; which begs the question: are we the only living creatures existing in this universe? Up until this moment, scientists have not found any evidence of living things in this universe except here on Earth, but there are many convincing arguments that propose we are not alone. Knowing that there are more planets in the universe than the sum of all sounds and words ever said by every human…

The planet Jupiter is one of the five objects to be visible from Earth in the solar system. Of these bodies it is the second largest behind the sun. Jupiter is the largest planet in the Solar System with a mass of 1.899x1027kg orbiting at 5.2AU from the Sun. Jupiter is orbited by 67 moons of which the first four are called the Galilean moons as of their discovery in 1614 by Galileo. Jupiter formed about 4.6billion years ago from the cloud of dust and gas that made up the early Solar System.…

However, will limiting our options to the recovery of earth and righting the wrongs done on this planet be beneficial in the face of the many possible catastrophic events, besides lack of resources and global warming, that can wipe out humanity and all life as it is known on earth, such as an epidemic or nuclear warfare? The answer is no, colonising…

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…

Mars otherwise known as the “red planet” because of the iron oxide surface on the planet that gives it a red color coat, is one point five hundred and twenty four astronomical units away from the sun. That’s one hundred and forty one point six million miles from the sun making it the fourth planet from the sun. It can easily be seen from Earth because of its red color. According to Nasa, “Mars is named for the ancient Roman god of war”. The Romans chose the name God Of War because it “resembles…

Kepler developed laws such as the three laws of planetary motion. He began to determine that the distance between the planets was a certain amount and not just purely random. He learned that each planet had a gravitational pull that attracted each planet towards each other although the thought of gravity had not been uncovered. This pull lead to the set amount of space between each planet. Kepler had also made discoveries about the sudden appearance of stars. One night he was watching through…

Mercury is a rocky planet and is the closest celestial body to the sun in our solar system. The planet is covered in many craters, boulders and pulverized dust. The planet lacks an atmosphere to help dictate temperature changes throughout a day, so the planet can experience many temperature swings multiple times per day. After a number of observations, it has been inferred that the planet has been geologically inactive for billions of years. There are no signs of dust storms, clouds, rivers…

Mercury 's Surface Geology: according to the information gathered by the probes sent to Mercury, this planet has a surface that resembles in some manner the surface of our Moon, with craters and maria as its most prominent features. Furthermore, there are other structures that, albeit not as common as impact craters, make up the surface of Mercury, such as vents - that are thought to be the source for magma-carved valleys on Mercury - and irregular depressions named "hollows", probably generated…
