second smallest planet in the solar system. It is 4‚879 kilometers across. Compare that with our moon‚ which is 3456 km across‚ and you can see that mercury is not very big. In fact‚ Jupiter’s moons Ganymede and Callisto and Saturn’s moon Titan are bigger! Even though those moons are bigger‚ Mercury weighs a lot more than they do because it is made of mostly metal and rock. In fact‚ Mercury has the most metals for its size of any planet in the solar system. Mercury is also the closest planet to the sun

other planets and other great wonders that happen so many kilometers away is now more than ever mesmerizing than when I was a little girl. Now‚ it is not only about the Sun‚ Moon‚ and Stars‚ but also about other great wonders across space such as comets‚ geysers‚ planets‚ and many moons. It is fascinating how the universe has many large and small planets with so many differences in structure but yet has so many similarities as to have been being built. From a documentary series‚ The Planets‚ the

The Sun (Star of the Family) Planet word comes from Greek ‚which means „wandering star“. Sun is the heaviest among Solar System. If we take total mass of whole Solar System‚ the Sun would be 99.86% of the total. Sun is a ball of hot‚burning gases. Sun is the nearest star to the Earth. Sun is the source of all energy for life on Earth. On the Sun’s surface‚ there are dark patches known as sunspots. These are patches of gas that looks dark since they are cooler than their surroundings. The light

Avatar Essay In the movie Avatar‚ the planet Pandora is similar to earth in many ways‚ yet it has many differences as well. The way Pandora looks highly resembles that way scientists theorize the way earth looked millions of years ago. This could be because the planet Pandora is in an early stage of development‚ or it could simply be because the Na’vi respect their environment and maintain the balance of life. They don’t pollute their environment and they let nature run its course freely. There

8. In both Hipparchian and Ptolemaic systems‚ the planets are assumed to move in a small circle called an epicycle‚ which in turn moves along a larger circle called a deferent. Both circles rotate clockwise and are roughly parallel to the plane of the Sun’s orbit (ecliptic). Despite the fact that the system is considered geocentric‚ the planets’ motion was not centered on the Earth but on what is called the eccentric. The orbits of planets in this system are epitrochoids. The epicycle rotated and

Space Colonization is survival of the human race off the planet Earth. Unfortunately‚ at the rate at which humans are destroying the Earth we are going to have to find another life sustaining planet very soon. Resources on Earth will inevitably run out‚ thus ending our tenure on Earth (unless new/different resources are used‚ climate gets under control‚ there is not a nuclear war/fallout‚ etc.)‚ and if we don’t have another planet ready for colonization or already colonized‚ the human race will become

simple sun-planet system.In the simple sun-planet system‚ I see that the sun is also moving around. Specifically‚ what happens to the central object (the Sun)?The sun is moving. It is moving because it is being pulled by the gravitational force that is between the sun and the planet. Can you explain why the central object moves? The central object moves because the sun is off to one side and the orbit is elliptical. HINT: Is gravitational attraction only the sun pulling on the planet? Does the

For example humans as Newton gives new ideas that contributed to the scientific revolution‚ like “The replacement of the Earth as center of the universe by heliocentric theory.” Moreover Isaac Newton explained the elliptical orbits of the planets and he advanced the law of universal gravitation. Furthermore Nicolaus Copernicus worked on the heliocentric model of the solar system‚ in which he tried to demonstrate that the sun was the center of the universe.
