The formation of our own Sun and planets probably was heavily influenced, if not triggered, by a nearby supernova explosion.

Planets move in ellipses with the Sun at one focus.

One theoretical model shows that young stars could power an outflow that matches what we see very closely.

The planets and moons of our solar system are blatantly visible because they reflect sunlight. Without the nearby Sun, these planets would be cryptic and dark on the sky.

The chemical and isotopic composition of the sun is the starting composition from which all planets formed.

Astronomy teaches the correct use of the sun and the planets.
