The sun is by far the largest object in our solar system, containing 99.8% of the solar system''s mass. It sheds most of the heat and light that makes life possible on Earth and possibly elsewhere.

How big is the Solar System?

Walk the Solar System. To walk the solar system you''ll need to convert the Astronomical Units to something walkable. If you multiply each distance from the Sun by 100cm you can easily walk and mark out the Solar System, although you will need a big open space. For example: Start with the Sun at 0 cm. Mercury 40 cm . Venus 70 cm. Earth 100 cm

OverviewFormation and evolutionGeneral characteristicsSunInner Solar SystemOuter Solar SystemTrans-Neptunian regionMiscellaneous populations

The Solar System is the gravitationally bound system of the Sun and the objects that orbit it. It formed about 4.6 billion years ago when a dense region of a molecular cloud collapsed, forming the Sun and a protoplanetary disc. The Sun is a typical star that maintains a balanced equilibrium by the fusion of hydrogen into helium at its core, releasing this energy from its outer photosphere. Astronomers

How Big Is the Solar System?

The far edge of the Oort Cloud is considered the edge of our Solar System, making our cosmic neighborhood quite big indeed.
