- 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 Beyond our own solar system, there are more planets than stars in the night sky

- 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
- The Day the Earth Smiled - NASA Solar System Exploration
On July 19, 2013, in an event celebrated the world over, NASA’s Cassini spacecraft slipped into Saturn’s shadow and turned to image the planet, seven of its moons, its rings — and, in the background, our home planet, Earth With the sun’s powerful and potentially damaging rays eclipsed by Saturn itself, Cassini’s onboard cameras were able to take advan-tage of this unique viewing
- Science - VERITAS Tabs – NASA Solar System Exploration
Science Studying Venus from atmosphere to core, VERITAS will seek answers to many of the lingering questions about Earth's sister world Does Venus have Earth-like continents that formed in the presence of water? Is its volcanism continuous, or does it come and go? Does the planet have plate tectonics?

Launch The Galileo spacecraft and its two-stage Inertial Upper Stage (IUS) were carried into Earth orbit on October 18, 1989 by space shuttle Atlantis on mission STS-34 The solid-fuel upper stage then accelerated the spacecraft out of Earth orbit toward the planet Venus for the first of three planetary flybys, or "gravity assists," designed to boost Galileo toward Jupiter In a gravity

The similarities don’t end there Each planet in the inner solar system is less dense than its inner neighbor – Mars is less dense than Earth, which is less dense than Venus, which is less dense than Mercury The Galilean moons follow the same principle, being less dense the farther they are from Jupiter
