What Did The Sun And All The Objects That Moves Around It Makeup
Our planetary arrangement is located in an outer spiral arm of the Galaxy milky way.
The Latest
Our solar organisation consists of our star, the Lord's day, and everything bound to information technology by gravity – the planets Mercury, Venus, Globe, 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, we take discovered thousands of planetary systems orbiting other stars in the Milky way.

10 Need-to-Know Things About the Solar Arrangement
one
One of Billions

2
Encounter Me in the Orion Arm
Our solar organisation orbits the middle of the Galaxy milky way at about 515,000 mph (828,000 kph). We're in one of the galaxy's four spiral artillery.
3
A Long Manner Round
It takes our solar organisation most 230 million years to complete i orbit around the galactic center.
4
Spiraling Through Space
There are 3 general kinds of galaxies: elliptical, spiral, and irregular. The Milky Way is a spiral galaxy.
five
Good Atmosphere(s)
Our solar system is a region of space. It has no atmosphere. But it contains many worlds – including Earth – with many kinds of atmospheres.
6
Many Moons
The planets of our solar organisation – and even some asteroids – hold more than 200 moons in their orbits.
7
Ring Worlds
The iv giant planets – and at to the lowest degree one asteroid – take rings. None are as spectacular as Saturn's gorgeous rings.
8
Leaving the Cradle
More than 300 robotic spacecraft have explored destinations beyond Earth's orbit, including 24 American astronauts who fabricated the trip from the Globe to the Moon.
nine
Life as We Know It
Our solar system is the only 1 known to support life. So far, nosotros merely know of life on Earth, but we're looking for more everywhere we can.
10
Far-Ranging Robots
NASA'south Voyager 1 and Voyager 2 are the only spacecraft to get out our solar arrangement. 3 other spacecraft – Pioneer 10, Pioneer xi, and New Horizons – volition eventually hit interstellar space.
FAQ: Which Spacecraft are Headed to Interstellar Space?
FAQ: Which Spacecraft are Headed to Interstellar Infinite?
Five spacecraft have achieved enough velocity to eventually travel beyond the boundaries of our solar system. Two of them reached the unexplored space between the stars afterward several decades in infinite.
- Voyager one went interstellar in 2012 and Voyager ii joined it in 2018. Both spacecraft are still in communication with Earth. Both spacecraft launched in 1977.
- NASA's New Horizons spacecraft is currently exploring an icy region beyond Neptune called the Kuiper Chugalug. It eventually volition leave our solar system.
- Pioneer x and Pioneer 11 besides will ultimately travel silently among the stars. The spacecraft used upward their ability supplies decades agone.
