Cosmic Distances

Light years also provide some helpful perspective on solar system distances: the Sun is about 8 light minutes from Earth. (And yes, there are also light seconds!)And because light from objects travels at light speed, when you see the Sun, or Jupiter or a distant star, you''re seeing it as it was when the light left it, be that 8 minutes, tens of minutes or 4.3 years ago.

Finding Life Beyond Earth is Within Reach

Many scientists believe we are not alone in the universe. It''s probable, they say, that life could have arisen on at least some of the billions of planets thought to exist in our galaxy alone — just as it did here on planet Earth. This basic question about our place in the Universe is one that may be answered by scientific investigations.

OverviewInner Solar SystemFormation and evolutionGeneral characteristicsSunOuter Solar SystemTrans-Neptunian regionMiscellaneous populations

The inner Solar System is the region comprising the terrestrial planets and the asteroids. Composed mainly of silicates and metals, the objects of the inner Solar System are relatively close to the Sun; the radius of this entire region is less than the distance between the orbits of Jupiter and Saturn. This region is within the frost line, which is a little less than 5 AU from the Sun.
