Beyond our solar system lies the Oort cloud. The Oort cloud is made of icy pieces of space debris the sizes of mountains and sometimes even larger. The Oort cloud is where some comets come from.

What's out there?

Way past Neptune's orbit, even past the Kuiper belt, what is there out there? Have you ever wondered? Watch this video to find out!

Where does the solar system end?

The solar system we call home has our sun, eight planets, all their moons, the asteroid belt, and lots of comets.

Outside Neptune's orbit is the Kuiper Belt. An almost empty ring around the sun that has icy bodies, almost all smaller than Pluto, making slow orbits around the sun.

But what's beyond the Kuiper belt?

Beyond the fringes of the Kuiper belt is the Oort Cloud. Unlike the orbits of the planets and the Kuiper Belt, which are pretty flat like a disk, It's a giant spherical shell surrounding the sun, planets, and Kuiper Belt Objects. Like a big bubble with thick walls around our solar system.

It's made of icy pieces of space debris the sizes of mountains and sometimes larger. This is where some comets come from.

The voyager 1 spacecraft took 35 years to leave the sun's magnetic influence. It's traveling one million miles each day. At that speed, it will take 300 years to reach the inner layer of the Oort Cloud. And then it will take 30,000 to get through it all. It's that thick.

The solar system consists of the Sun, with planets and smaller objects such as asteroids and comets in orbit around it.

Pluto and the dwarf planets

Scientists have discovered other objects orbiting the Sun. These include comets, asteroids, and dwarf planets like Pluto and Ceres. Pluto used to be considered the ninth planet in our solar system, but in 2006 scientists reclassified it as a dwarf planet. So now we have eight planets in the solar system.

Satellites

A satellite is an object in orbit around a planet. The Moon is the Earth's natural satellite, but humans have launched many artificial satellites into orbit.

is a force that attracts objects towards each other. The more mass an object has, the greater its force of gravity:

gravity forces between the Earth and the Moon keep the Moon in orbit around the Earth

gravity forces between the Sun and the Earth keep the Earth in orbit around the Sun

An overview of how the solar system as a whole formed. Alessandro Morbidelli, CNRS (France)

One of the big questions humans have is "how did life begin on Earth?". The key to answer this question is understanding how the Earth-Moon system formed and how the Solar System as a whole formed. We can use mathematical models to understand it, but we need data to form the basis for the models. We can use observations of the Solar System to develop these models, but rocks are also important, because they can be analysed in the laboratory and measured in detail to determine their chemical composition and when they formed.
