The Sun

Damage
The Sun does extreme damage to any planet that touches, similarly to the invisible asteroid barrier. This damage is high enough to destroy any building and do huge soil damage.

Health
The Sun has over 2000 health, and thus can take multiple shots from even the most powerful weapons in the game.

Damaging and Destroying the Sun
When a weapon, planet, or asteroid hits the sun, it will glow a darker red. The sun has multiple stage - each stage with the sun becoming redder. Each time the stage changes, plasma tendrils branch off from the sun. On the final stage, it will have long spikes that come off of it. When destroyed, The Sun will split into several red fragments launched at a high speed throughout the solar system, dealing 65 damage, similar to those created when a planet is destroyed. The Sun will disappear, leaving behind a black hole.

Black Hole
The black hole cannot be damaged, as it does not collide with anything. When the black hole is present, planets will take constant soil damage, but no extra building damage.

Sun Derailing
The sun can be derailed, like planets, but with three differences. Derailing the sun does NOT change the orbit path of the planets.
 * 1) Takes multiple hits to derail the first time.
 * 2) The sun has a much higher mass than a planet. (It is affected less by world rammers).
 * 3) The sun bounces back after touching the asteroid belt
