Uranus Uranus Uranus is the seventh planet from the Sun and has the third-largest planetary radius and fourth-largest planetary mass in the Solar System. Though it is visible to the naked eye like the five classical planets‚ it was never recognized as a planet by ancient observers because of its dimness and slow orbit. It was the first planet to be discovered in modern history. It was discovered in 1781 by Sir William Herschel (Encyclopedia: Uranus (planet)) and expanded the known boundaries of

There are three confirmed and two other possible planets that orbit Gliese 581. Each of these five planets are close to the star and have a circular orbit. The planets orbiting Gliese 581 were named in the order they were discovered and are named Gliese e‚ Gliese b‚ Gliese c‚ Gliese g‚ and Gliese d. The mass of Gliese 581e is 1.9 times the mass of Earth‚ Gliese

most of us think of eight planets orbiting around the sun. However‚ the solar system is a lot more complicated‚ larger and exciting than this simple description. The solar system is a gravitationally bound system with all the objects in this system revolving around the sun. The eight planets revolving around the sun are: Mercury‚ Venus‚ Earth‚ Mars‚ Jupitar‚ Saturn‚ Neputune‚ Uranus and Pluto. However‚ the solar system also consists of moons‚ asteroids‚ comets‚ minor planets‚ dust and gas. The sun makes

Special feauture Description Uranus was the first planet to be discovered in modern history. It was actually discovered by accident in 1781 by William Herschel. Like the other gas giants‚ Uranus has a very thick cloud cover and an atmosphere made up mostly of hydrogen‚ helium‚ methane‚ and ammonia. The

Orbital change‚ rotational change‚ collisions with the Earth‚ the big rip‚ the sun‚ black holes‚ and other systems going out of whack can cause events that could potentially cause an end to life on Earth.
