- 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
- Planet Compare - NASA Solar System Exploration
NASA’s real-time science encyclopedia of deep space exploration Our scientists and far-ranging robots explore the wild frontiers of our solar system
- In Depth | Our Solar System – NASA Solar System Exploration
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
- In Depth | Moons – NASA Solar System Exploration
Of the terrestrial (rocky) planets of the inner solar system, neither Mercury nor Venus have any moons at all, Earth has one and Mars has its two small moons In the outer solar system, the gas giants Jupiter and Saturn and the ice giants Uranus and Neptune have dozens of moons
- Solar System Exploration
The solar system has one star, eight planets, five dwarf planets, at least 290 moons, more than 1 3 million asteroids, and about 3,900 comets
- Bibliography - NASA Solar System Exploration
We use a best of approach with images, selecting a key set of images that best tell the story of the planet, celestial object or spacecraft Comprehensive planetary image libraries can be found at http: photojournal jpl nasa gov and http: hubblesite org gallery
- In Depth | Asteroids – NASA Solar System Exploration
The orbits of asteroids can be changed by Jupiter's massive gravity – and by occasional close encounters with Mars or other objects These encounters can knock asteroids out of the main belt, and hurl them into space in all directions across the orbits of the other planets

- In Depth | Earths Moon – NASA Solar System Exploration
The leading theory of the Moon's origin is that a Mars-sized body collided with Earth about 4 5 billion years ago The resulting debris from both Earth and the impactor accumulated to form our natural satellite 239,000 miles (384,000 kilometers) away
- Spacecraft Power FS 10-8-98 v2 - NASA Solar System Exploration
By aiming a spacecraft so that it passes very close to a planet or moon, it is possible to boost the spacecraft on to more distant desti-nations with greater velocity
