Did any planets explode?

We know stars can go supernova, but can the same thing happen to a planet? While some planets have boiling hot cores, this is not enough to cause a planet to shatter let alone suddenly explode. As far as astronomers know, there is no internal mechanism or other phenomenon that could ever cause a planet to fly apart.

Is it possible for a planet to explode?

Most planets can exist for a long, long time, but they can’t last forever. Hungry stars and violent planetary neighbors can completely destroy a world, while impacts and excessive volcanism can render a habitable world sterile by stripping the planet of its water.

Will the Sun eventually destroy Earth?

By that point, all life on Earth will be extinct. The most probable fate of the planet is absorption by the Sun in about 7.5 billion years, after the star has entered the red giant phase and expanded beyond the planet’s current orbit.

How is 1 hour in Space 7 years on Earth?

The first planet they land on is close to a supermassive black hole, dubbed Gargantuan, whose gravitational pull causes massive waves on the planet that toss their spacecraft about. Its proximity to the black hole also causes an extreme time dilation, where one hour on the distant planet equals 7 years on Earth.
