Universe
In a Froth of Galaxies
On the Outskirts of a Supercluster
In the Local Group
Embedded in the Milky Way's Disk
On the Inner Edge of the Local Arm
On the 3rd Planet from the Sun
| Percentage Contribution to Solar System Mass | Sun | 99.900% | Jupiter | 0.099% | All the rest | 0.001% |
Apart from the Sun, there is very little matter in the Solar system. One of those specks, the pale blue world three out from the Sun, a rocky planet with four fifths of its surface covered by ocean, is home to six billion people, our place, Earth.
We've just begun to look. So far, we have yet to find another place like it.
