Which planet has two moons
Take Me with You by Catherine Ryan HydeAugust Shroeder, a burned-out teacher, has been sober since his 19-year-old son died. Every year hes spent the summer on the road, but making it to Yellowstone this year means everything. The plan had been to travel there with his son, but now August is making the trip with Philips ashes instead. An unexpected twist of fate lands August with two extra passengers for his journey, two half-orphans with nowhere else to go.
What none of them could have known was how transformative both the trip and the bonds that develop between them would prove, driving each to create a new destiny together.
Why Does Jupiter Have 79 Moons, But Earth Only Has One? - Unveiled
Why Does Jupiter Have 79 Moons When Earth Just Has One?
Natural satellites or moons orbit some of the planets of the solar system. The Moon is Earth's only natural satellite. However, some planets have more than one moon. Jupiter has the most moons of any planet in the solar system. Jupiter has 79 moons. Of these, 72 have confirmed orbits and 52 have been named.

Of the four rocky, terrestrial planets, only Mars has more than one moon. The two small bodies that orbit the red planet are both smaller than Earth's moon, and raise a number of questions about the formation of the early solar system. Phobos and Deimos bear more resemblance to asteroids than to Earth's moon. Both are tiny — the larger, Phobos, is only 14 miles across 22 kilometers , while the smaller, Deimos, is only 8 miles 13 km , making them some of the smallest moons in the solar system. Both are also made up of material that resembles Type I or II carbonaceous chondrites, the substance that makes up asteroids.
The Solar System 's planets and officially recognized dwarf planets are known to be orbited by natural satellites , or moons. Moons are classed in two separate categories according to their orbits: regular moons, which have prograde orbits they orbit in the direction of their planets' rotation and lie close to the plane of their equators, and irregular moons, whose orbits can be pro- or retrograde against the direction of their planets' rotation and often lie at extreme angles to their planets' equators. Irregular moons are probably minor planets that have been captured from surrounding space. Most irregular moons are less than 10 kilometres 6. The earliest published discovery of a moon other than the Earth's was by Galileo Galilei , who discovered the four Galilean moons orbiting Jupiter in Over the following three centuries only a few more moons were discovered. Missions to other planets in the s, most notably the Voyager 1 and 2 missions, saw a surge in the number of moons detected, and observations since the year , using mostly large, ground-based optical telescopes , have discovered many more, all of which are irregular.
Earth only has one moon , but dozens of natural satellites revolve around Jupiter, the biggest planet in our solar system. And new members in the Jupiter posse are still being discovered. On July 16, , it was announced that a team of astronomers had found 12 previously unknown moons around the planet. The big find happened last year. Scott S.
