Temperature on Earth. Earth is the most unique planet in the Solar System because it is the only one that can support life as we know it. Its dense atmosphere serves to protect life on Earth by filtering harmful ultra-violet rays from hitting the surface and vaporizing most meteors before they can strike. In addition, the planetâs average temperatures are comfortable enough to support life. Earthâs life-sustaining conditions are seen as fortuitous. If the planet had been just 5% closer to the Sun; the surface would have been too hot while if it had been just 1% farther the surface would be a frozen wasteland.
