How far is the Death Star from Earth?

In this case, the Death Star is farther away, with an orbital distance of 1.564 x 10⁶ meters. I assume they just moved it closer to the planet in the animation for effect.

How long does it take for the Death Star to destroy a planet?

For starters, we know that the planet-annihilating Death Star uses a single pulse from a laser-like apparition to destroy its target in just a few seconds. (Alderaan was gone in 3).

What happens when a star collapses in on itself?

A star about eight times the sun’s mass collapsed in on itself and sent its outer envelope of gas out into interstellar space, forming a nebula of heavy elements and other debris before collapsing into either a neutron star or a black hole. It remains the only nearby supernova astronomers have seen in modern times.

What would happen if two neutron stars collide?

From certain death to a scientific goldmine, here’s the spectrum of possibilities that we might expect from merging black holes, colliding neutron stars or detonating supernovae in our galactic neighborhood An illustration of a “kilonova,” a hot, dense expanding cloud of debris produced by the collision of two neutron stars.

What would happen if Earth was blasted apart by a pinwheel?

Although the pinwheel can’t blast Earth apart like the Death Star from Star Wars — at least not from 8,000 light years away — it could still cause mass extinction or possibly even threaten life as we know it on our planet. Gamma rays would not penetrate Earth’s atmosphere well to burn the ground, but they would chemically damage the stratosphere.

What happens when two planets collide in outer space?

Such collisions are thought to produce much of the universe’s gold, platinum and other elements heavier than iron. But they can also have catastrophic consequences for any nearby habitable planets. Credit: NASA’s Goddard Space Flight Center and CI Lab
