In Depth | Our Solar System – NASA Solar System Exploration
There are more than 200 known moons in our solar system and several more awaiting confirmation of discovery. Of the eight planets, Mercury and Venus are the only ones with no moons. The giant planets Jupiter and Saturn lead our solar system’s moon counts.
In Depth | Oumuamua – NASA Solar System Exploration
The first known interstellar object to visit our solar system, 1I/2017 U1 ‘Oumuamua, was discovered Oct. 19, 2017 by the University of Hawaii’s Pan-STARRS1 telescope, funded by NASA’s Near-Earth Object Observations (NEOO) Program, which finds and tracks asteroids and comets in Earth’s neighborhood. While originally classified as a comet ...

In Depth | Pluto – NASA Solar System Exploration
Discovered in 1930, Pluto was long considered our solar system's ninth planet. But after the discovery of similar intriguing worlds deeper in the distant Kuiper Belt, icy Pluto was reclassified as a dwarf planet.
In Depth | Eris – NASA Solar System Exploration
Dwarf planet Eris is a member of a group of objects that orbit in a disc-like zone beyond the orbit of Neptune called the Kuiper Belt. This distant realm is populated with thousands of miniature icy worlds, which formed early in the history of our solar system about 4.5 billion years ago.
Enceladus | Science – NASA Solar System Exploration
Scientists discovered evidence of Enceladus’ internal ocean from gravity measurements based on the Doppler effect and the magnitude of the moon’s very slight wobble as it orbits Saturn. The data was consistent with the existence of a large global ocean inside the moon.
Rings | Science – NASA Solar System Exploration
In the 400 years since Galileo's discovery, the rings have become Saturn’s telltale feature and are perhaps the most recognized characteristic of any world in our solar system. Cassini spent more than a decade examining them more closely than any spacecraft has before.
