- In Depth | Our Solar System – NASA Solar System Exploration
The planetary system we call home is located in an outer spiral arm of the Milky Way galaxy Our solar system consists of our star, the Sun, and everything bound to it by gravity – the planets Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune; dwarf planets such as Pluto; dozens of moons; and millions of asteroids, comets, and meteoroids Beyond our own solar system, there are more planets than stars in the night sky So far, we have discovered thousands of planetary
- In Depth | Kuiper Belt – NASA Solar System Exploration
The amount of material in the Kuiper Belt today might be just a small fraction of what was originally there According to one well-supported theory, the shifting orbits of the four giant planets (Jupiter, Saturn, Uranus, and Neptune) could have caused most of the original material -- likely 7 to 10 times the mass of Earth – to be lost
- In Depth | Moons – NASA Solar System Exploration
In the outer solar system, the gas giants Jupiter and Saturn and the ice giants Uranus and Neptune have dozens of moons As these planets grew in the early solar system, they were able to capture smaller objects with their large gravitational fields

- The Forces that Sculpt Saturns Rings - NASA Solar System Exploration
Saturn’s rings are a truly alien environment, consisting of many small bodies in orbit around the planet
- Mars By the Numbers - NASA Solar System Exploration
Mars is the fourth planet from the Sun, and the seventh largest It’s the only planet we know of inhabited entirely by robots
- In Depth | Enceladus – NASA Solar System Exploration
Also, like some other moons in the extensive systems of the giant planets, Enceladus is trapped in what’s called an orbital resonance, which is when two or more moons line up with their parent planet at regular intervals and interact gravitationally Enceladus orbits Saturn twice every time Dione, a larger moon, orbits once
- In Depth | Io – NASA Solar System Exploration
Discovery Io was discovered on Jan 8, 1610 by Galileo Galilei The discovery, along with three other Jovian moons, was the first time a moon was discovered orbiting a planet other than Earth The discovery of the four Galilean satellites eventually led to the understanding that planets in our solar system orbit the Sun, instead of our solar system revolving around Earth Galileo apparently had observed Io on Jan 7, 1610, but had been unable to differentiate between Io and Europa until the
- In Depth | Titan – NASA Solar System Exploration
In Depth Saturn's largest moon, Titan, is an icy world whose surface is completely obscured by a golden hazy atmosphere Titan is the second largest moon in our solar system Only Jupiter's moon Ganymede is larger, by just 2 percent Titan is bigger than Earth's moon, and larger than even the planet Mercury
