Uranus (Caelus), discovered in 1781, takes 84 Earth years to revolve around the sun. It is notable for its 11 small rings, its bluish hue and the fact that its axis of rotation is nearly horizontal, as if it had been knocked over. In fact, some astronomers believe a collision with an...
And researchers have discovered planets orbiting Gliese 581. These exoplanets have been named, ready? Gliese 581 b, c, d, e, in alphabetical order of their discovery. Gliese 581 d and e are the planets I wanna focus on now. See, in 2009, a group of researchers made an announcement. ...
These missions provided data on the Great Red Spot, revealed volcanoes on Io, helped create the first detailed maps of the Galilean satellites, discovered Jupiter’s rings, and provided close-up photos of the planet and largest moons. Future exploration will include the ice-covered liquid ocean ...
Scientists may now be closer than ever to answering that question.Using powerful telescopes, a team of astronomers in South Americ a discovered a new planet, called Proxim a b.It circles a star named Proxim a Centauri, in the same way Earth circles the sun. Proxim a Centauri is the ...
Using powerful telescopes, a team of astronomers in South America discovered a new planet, called Proxima b. It circles a star named Proxima Centauri, in the same way Earth circles the sun. Proxima Centauri is the closest star to our solar system. ...
These moons — Io, Europa, Ganymede, and Callisto — were first discovered by Galileo in 1610, so they are sometimes referred to as the Galilean moons (Figure below). The Galilean moons are larger than the dwarf planets Pluto, Ceres, and Eris. Ganymede is not only the biggest moon in ...

Saturn, would actually float inwater. Each of the outer planets has a magnetic field, aring system, and many known moons, with more likely to be discovered. Pluto has no known rings and only five known moons. Several other Kuiper belt objects and some asteroids also have moons of their ow...
Ceres, a round object in the Asteroid Belt between Mars and Jupiter, also got the boot. Ceres was considered a planet when it was discovered in 1801, but it was later deemed to be anasteroid. That still didn't quite fit because it was so much larger (and rounder) than the other aste...
