Can a planet collapse on itself?

Because planets don’t have enough mass to collapses on themselves. Stars, when they run out of fuel for fusion, collapse onto themselves because of their immense mass.

How big would the Earth be if it was a black hole?

After just a few minutes more — 21 to 22 minutes total — the entire mass of the Earth would have collapsed into a black hole just 1.75 centimeters (0.69”) in diameter: the inevitable result of an Earth’s mass worth of material collapsing into a black hole.

How small would the Sun have to be to be a black hole?

The Schwarzschild radius of the sun is approx. 3 km. It would be a black hole if all the mass of it were within the 3km.

What would be the radius of the sun if it could be condensed into a black hole?

If the Sun, with its mass of 1 MSun, were to become a black hole (fortunately, it can’t—this is just a thought experiment), the Schwarzschild radius would be about 3 kilometers; thus, the entire black hole would be about one-third the size of a neutron star of that same mass.

What if Earth fell into a black hole?

If Earth got close enough, the side nearest to the black hole would begin stretching toward it. Our atmosphere would start to be vacuumed up. If Earth managed to fall into the orbit of the black hole, we’d experience tidal heating. The strong uneven gravitational pull on the Earth would continuously deform the planet.

How fast would a black hole destroy Earth?

Theoretically if there was no spin or outward pressure to take into consideration, Heile said, it would take about 10 to 15 minutes for the entire Earth to fall into the black hole.

Could the Earth survive a black hole?

As matter gets sucked into the black hole, it generates massive amounts of radiation. So, even if we somehow survived all the asteroids, we’d likely die from the radiation. While this may be a possibility with a black hole and our Sun, the extreme tidal forces would most likely make our planet inhabitable.

What would happen if the Earth collapsed into a black hole?

After just a few minutes more — 21 to 22 minutes total — the entire mass of the Earth would have collapsed into a black hole just 1.75 centimeters (0.69”) in diameter: the inevitable result of an Earth’s mass worth of material collapsing into a black hole. When matter collapses, it can inevitably form a black hole.

How big can a planet be?

(23 January 2018 – Johns Hopkins University) A planet can be no bigger than about 10 times the mass of Jupiter, an astrophysicist has concluded. Of course, that’s pretty darned massive. Jupiter carries almost 318 times the mass of Earth, making the most massive planets possible the equivalent of nearly 3,200 Earths.

Why doesn’t the Earth collapse on itself?

Gravity is a good and strong enough force that you’re right, the Earth should collapse on itself, but the reason why they don’t do so is because the gravity isn’t strong enough to overcome the inter-electronic repulsing forces which are by at least a magnitude of 10 30 for unit values.

How big is Jupiter compared to Earth?

Jupiter carries almost 318 times the mass of Earth, making the most massive planets possible the equivalent of nearly 3,200 Earths. Most of the public controversy about the definition of a planet has focused on Pluto, which weighs in at only about 0.2 percent of Earth’s mass.
