By James About 1,300,ooo earth would fit inside of the sun In about 130 million more years and the sun will consume the earth soon the sun will collapse in it self and will be the size of are planet Mercury is the smallest plant in the universe it is 4,879 across Living on mercury for a year is only 88 days Did you know that mercury has wrinkles Did you know that a day on Venus is longer then a year Venus is often called earths sister planet Last thing is Venus rotates in the opposite direction to most planets Did you know that earth rotation is gradually slowing A long time a go earth was believed to be the center of the solar system Earth has a powerful magnetic field Did you know that Mars and earth have the same land mass Mars is home to the tallest mountain in the solar system Only 18 missions to Mars have been successful Jupiter is the fourth brightest object in the solar system The ancient Babylonians were the first to record their sighting of Jupiter Jupiter has the shortest day of all the planets Saturn can be seen with the naked eye Saturn was known to the ancients including the Babylonians and far Eastern observers Saturn is the flattest planet Uranus was officially discovered by Sir William Herschel in 1781 Uranus turns on its axis once every 17 hours 14 minutes Uranus makes one trip around the sun every 84 Earth years Neptune was not known to the ancients Neptune spins on its axis very rapidly Neptune is the smallest of the ice giants The dark side of the moon is a myth The rise and fall of the tides on earth is caused by the moon The Moon is drifting away from the Earth Pluto is named after the Greek god of the underworld Pluto was reclassified from a plant to a dwarf plant in 2006 Pluto was discovered on February 18th 1930 by the Lowell Observatory The closer you are to a black hole the slower time moves Stars and all sort of things can get suck in to a black hole The point of no return is called event horizon While asteroid impacts were more common in the past they aren't as frequent today An Asteroid impact some 65 million years ago contributed to the extinction of the dinosaurs Earth suffers an impact from an abject the size of a football field about once every 2,000 years The nucleus of a comet is made of ice and can be as small as a few meters across to giant boulder a few kilometers across The closest point in a comets orbit to the sun is called perihelion. The most distant point is called aphelion Comet orbits are usually elliptical Millions of meteoroids travel through Earths atmosphere each day When a meteor encounters our atmosphere and is vaporized it leaves behind a trail. That burning meteoroid is called a meteor The appearance of a number of meteors occurring in the same part of the sky over a period of time is called meteor shower Every star you see in the night sky is bigger and brighter than our sun You cant see millions of stars on a dark night Stars are black bodies Phobos,s orbit is so fast it would appear to an observer on the planet to rise in the west and set in the East twice each Martian day. Neither Phobos nor Deimos have atmospheres. They are to small with no volatiles to create an atmosphere and their gravity too low to retain one Lo has more than 400 active volcanoes on its surface
