Planet Earth has existed about as long as the Solar System - something like 4.6 billion years. For the future, it is harder to know how long it will last. In a few hundred million years, it is expected to get too hot for life to exist on planet Earth, but the planet will continue existing. In 4 or 5 billion years, Earth will ultimately be swallowed up by the expanding Sun.

It reduces the Life span.
We're currently only aware of one planet that supports any life. That planet is Earth, the one you're presumably on right now. Since this is the only planet with life, it has both the longest and the shortest life span. Life span varies depending on what organism you're talking about. The human life span -- the longest a human is confirmed to have lived -- is approximately 122 years old. Life span is different than life expectancy. Life expectancy is the average length of a human life, and it varies widely based on factors such as geography, poverty, gender, race, etc. If you went to any other planet in our solar system without proper protective equipment (spacesuit, etc.), your life expectancy would be exceedingly small.
