10 Things About Our Solar System''s Most Marvelous Moons

The most famous geysers in our solar system outside of Earth belong to Saturn''s active moon Enceladus. It''s a small, icy body, but Cassini revealed this world to be one of the solar system''s most scientifically interesting destinations. Geyser-like jets spew water vapor and ice particles from an underground ocean beneath the icy crust of Enceladus.

The brightest and largest object in our night sky, the Moon makes Earth a more livable planet by moderating our home planet''s wobble on its axis, leading to a relatively stable climate. It also

How the Moon Formed

Several theories about our Moon''s formation vie for dominance, but almost all share that point in common: near the time of the solar system''s formation, about 4.5 billion years ago, something ― perhaps a single object the size of Mars, perhaps a series of objects ― crashed into the young Earth and flung enough molten and vaporized debris into space to create the Moon.

What Is The Largest Moon In The Solar System?

The largest moon in the solar system is Jupiter''s moon, Ganymede. With a diameter of 3,273-miles (5,268-kilometres), it is larger than the planet Mercury. Like most moons in our solar system, Ganymede has no rotation. Rather, Ganymede is tidally locked to Jupiter, meaning that one side always faces the gas giant while the other side

What Is the Solar System?

There are about 300 known moons in the solar system. The technical term for a moon is a natural satellite. (A satellite is a small body that orbits a larger one Astronomers speculate there may be more things beyond the Kuiper Belt that are part of our solar system. These speculations include a possible ninth planet, which is sometimes

The Planets In Order | From The Sun, Information, History

In our Solar System, there are eight planets. The planets in order from the Sun based on their distance are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune. however, the smallest planet out of the eight. It is slightly larger than our Moon but smaller than Ganymede – one of Jupiter''s moons. Mercury itself doesn''t

10 Largest Moons in the Solar System

The tenth largest moon in the solar system is the second largest orbiting Uranus. Thanks to modern science, we know more about the Moon than ever. Our moon makes life possible because it stabilizes our orbit. Without it, the environment would be too chaotic for life as we know it to exist. Life could not exist on the moon. The atmosphere is

Not That Small: Ranking the 10 Largest Moons in Our Solar System

The largest moon in our solar system is also the only moon with its own magnetic field, which causes auroras like our Northern and Southern Lights in its north and south poles. It has large, bright regions of ridges and grooves that cut across older, darker regions which indicate that the moon experienced dramatic tectonic shifts in the distant

The Moon is a very slightly scalene ellipsoid due to tidal stretching, with its long axis displaced 30° from facing the Earth, due to gravitational anomalies from impact basins. Its shape is more elongated than current tidal forces can account for. This ''fossil bulge'' indicates that the Moon solidified when it orbited at half its current distance to the Earth, and that it is now too cold for its shape to restore

Where did the Moon come from?

The Capture Theory: This theory proposes that the Moon was formed somewhere else in the solar system, and was later captured by the gravitational field of the Earth. The Moon''s different chemical composition could be explained if it formed elsewhere in the solar system, however, capture into the Moon''s present orbit is very improbable

Planet Sizes and Locations in Our Solar System

Mars, the red planet, is the seventh largest planet in our solar system. Mars is about half the width of Earth, and has an equatorial diameter of about 4,221 miles (6,792 kilometers). Mars is the fourth planet from the Sun, orbiting at an average distance of 141.6 million miles (227.9 million kilometers).

How Many Moons Does Each Planet Have?

· Jupiter also has the biggest moon in our solar system, Ganymede. These moons are so big you can see them with just a pair of binoculars. Saturn. As of June 8, 2023, Saturn has 146 moons. And that''s not counting Saturn''s beautiful rings! Saturn''s moons have great names like Mimas, Enceladus, and Tethys. One of these moons, named Titan

In Depth | Triton – NASA Solar System Exploration

It is unusual because it is the only large moon in our solar system that orbits in the opposite direction of its planet''s rotation―a retrograde orbit. Scientists think Triton is a Kuiper Belt Object captured by Neptune''s gravity millions of years ago. It shares many similarities with Pluto, the best known world of the Kuiper Belt.

List Of The Solar System''s 30 Biggest Moons

Biggest To Smallest. Here you can learn about the 30 largest moons (by diameter) in the solar system! There are over 180 moons that orbit the planets and dwarf planets. The largest 19 moons in the list below are large enough to have been rounded by their own gravity (this is called being in hydrostatic equilibrium).If these moons were directly orbiting the Sun, that''d be referred to as

The giant planets Jupiter and Saturn lead our solar system''s moon counts. In some ways, the swarms of moons around these worlds resemble mini versions of our solar system. Pluto, smaller than our own moon, has five moons in its orbit, including the Charon, a moon so large it makes Pluto wobble. Even tiny asteroids can have moons.

Meet our Solar System

The Moon is the only other body in our solar system that has been explored by humans. Twenty-four NASA astronauts have visited the Moon, on Apollo 11-17. NASA also sent Apollo 8 and 10 to orbit the Moon, preparing for the lunar landings.

In Depth | Titan – NASA Solar System Exploration

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.

In Depth | Moons – NASA Solar System Exploration

Most moons in our solar system are named for mythological characters from a wide variety of cultures. Newer moons discovered at Saturn, for example, Titan, the second largest in the solar system, is the only moon with a thick atmosphere. In the realm of the ice giants, Uranus''s inner moons appear to be about half water ice and half rock.
