exist on a planet in the Beta Pictoris system? First‚ one must ask‚ Are there planets in the Beta Pictoris system?. However‚ that question would be impossible to answer if one did not answer the most basic questions first; Where do planets come from? and do the key elements and situations‚ needed to form planets‚ exist in the Beta Pictoris system?. To understand where planets come from‚ one has to first look at where the planets in our solar system came from. Does or did our star‚ the sun

Saturn is the second largest planet in the solar system. Because Saturn is bigger than Earth‚ you would weigh more on Saturn. If you weigh 100 pounds on Earth you would weigh 112 on Saturn. The Romans gave the planet Saturn its name after their god of agriculture. Saturn is 74‚899 miles wide (120‚535 kilometers wide). It takes Saturn ten hours and forty minutes to complete one single rotation‚ isn ’t that cool! One day on Saturn is only ten hours long‚ ours is twenty-four hours long. Thirty years

Gravity is the force that keeps objects close to the earth Not only does gravity keep objects close to the earth it also keeps the solar system revolving the sun Gravity was discovered by Isaac Newton Acceleration of objects that is due to gravity on Earth is 9.8 m/s Also‚ according to Mr. Newton’s First Law‚ once the egg was moving‚ it didn’t want to stop. The container of water interrupted the egg’s fall‚ providing a safe place for the egg to stop moving so you could recover it unbroken

How many planets are there in our solar system? Our solar system has nine planets and one star: the Sun. In order from the Sun out‚ the planets are: Mercury‚ Venus‚ Earth‚ Mars‚ Jupiter‚ Saturn‚ Uranus‚ Neptune and Pluto. A popular mnemonic used to remember the planets in order is: My Very Educated

* Today we know Solar system has: 1 star‚ 8 planets‚ 5 dwarf planets‚ 139+ moons‚ countless small solar system bodies * A major lesson from all this is that the solar system is almost entirely made of nearly empty space * All planets orbit the sun in the same direction (counter-clockwise) * Most rotate in the same direction * Venus rotates backward * Uranus rotates on its side (equator perpendicular to equator) * nearly all the moons in the solar system‚ including Earth’s

To be considered a planet of our solar system you need many different aspects which may seem effortless to understand although there is endless information which is new to scientists everyday. Pluto has some but certainly not all the qualities as it was found orbiting the Kuiper belt which is beyond the orbit of Neptune‚ the current furthest planet from the sun. Pluto has been one of the 9 planets in the past‚ but now that scientists have higher tech machines and programmes to allow them to explore
