Our Solar System
For what reason is it Called the Solar System?
There are numerous planetary frameworks like our own in the universe, with planets circling a host star. Our planetary framework is named the "nearby planet group" on the grounds that our Sun is named Sol, after the Latin word for Sun, "solis," and anything identified with the Sun we call "sun oriented."
Our planetary framework is situated in an external winding arm of the Milky Way cosmic system.
Our planetary group comprises of our star, the Sun, and everything bound to it by gravity – the planets Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune; bantam planets like Pluto; many moons; and a large number of space rocks, comets, and meteoroids. Past our own nearby planet group, we have found a huge number of planetary frameworks circling different stars in the Milky Way.

10 Need-to-Know Things About the Solar System
1
ONE OF BILLIONS
Our planetary group is comprised of a star, eight planets, and endless more modest bodies, for example, bantam planets, space rocks, and comets.
2
MEET ME IN THE ORION ARM
Our nearby planet group circles the focal point of the Milky Way cosmic system at around 515,000 mph (828,000 kph). We're in one of the world's four winding arms.
3
A LONG WAY ROUND
It takes our nearby planet group around 230 million years to finish one circle around the galactic focus.
4
SPIRALING THROUGH SPACE
There are three general sorts of cosmic systems: curved, twisting, and unpredictable. The Milky Way is a winding universe.
5
Great ATMOSPHERE(S)
Our nearby planet group is a locale of room. It has no environment. Yet, it contains numerous universes – incorporating Earth – with numerous sorts of environments.
6
MANY MOONS
7
RING WORLDS
The four monster planets – and no less than one space rock – have rings. None are pretty much as breathtaking as Saturn's perfect rings.
8
LEAVING THE CRADLE
In excess of 300 automated shuttle have investigated objections past Earth's circle, including 24 American space explorers who made the excursion from the Earth to the Moon.
9
LIFE AS WE KNOW IT
Our nearby planet group is the just one known to help life. Up until now, we just know about existence on Earth, yet we're searching for all the more wherever we can.

FAR-RANGING ROBOTS
NASA's Voyager 1 and Voyager 2 are the main space apparatus to leave our planetary group. Three other rocket – Pioneer 10, Pioneer 11, and New Horizons – will ultimately hit interstellar space.
FAQ: Which Spacecraft are Headed to Interstellar Space?
Five rocket have accomplished sufficient speed to ultimately go past the limits of our planetary group. Two of them arrived at the neglected space between the stars following quite a few years in space.
Explorer 1 went interstellar in 2012 and Voyager 2 went along with it in 2018. Both rocket are as yet in correspondence with Earth. Both space apparatus dispatched in 1977.
NASA's New Horizons rocket is presently investigating a cold district past Neptune called the Kuiper Belt. It in the long run will leave our planetary group.
Pioneer 10 and Pioneer 11 additionally will at last travel quietly among the stars. The shuttle spent their force supplies many years prior.
