it’s unlikely that the Sun contains a black hole, and if it does, it would be extremely small.
According to NASA, the Sun is too small to become a black hole and would need to be about 20 times more massive to do so.
In billions of years, the Sun will become a red giant star and then a planetary nebula. The Sun’s core will form a white dwarf, a dense ball of carbon and oxygen that no longer produces nuclear energy.
Based on the helioseismology studies we’ve done, there is almost certainly NOT a black hole in our Sun. Or if there is, it would need to be exceedingly tiny. So there’s no need to pack your bug-out bag for a solar doomsday
Instead, the Sun will become a dense stellar remnant, a white dwarf. As it exhausts its hydrogen fuel, the Sun will start burning helium, swell in size, and briefly become a red giant.
Black holes are nearly undetectable unless they are feeding on space stuff or tugging on nearby stars.
The Sun would become a black hole if its mass was contained within a sphere about 2.5 km across
A black hole’s physical size must be less than the Schwarzschild radius. For example, a black hole the size of Earth would have a radius of less than one inch, making it about as big as a ping pong ball. The Sun, on the other hand, would have a radius of just under two miles.
According to NASA, if the Sun was replaced with a black hole that had the same mass as the Sun, the Schwarzschild radius would be 3 km
Some black holes are larger than the Sun:
- Stellar-mass black holes: These black holes are typically 10–100 times the mass of the Sun.
- Intermediate-mass black holes: These black holes range from 100–100,000 times the mass of the Sun.
- Supermassive black holes: These black holes can be millions or billions of times the mass of the Sun. The supermassive black hole at the center of the Milky Way is 4.3 million solar masses.
However, black holes are tiny compared to their host galaxies. They make up less than 1% of the mass of a typical galaxy and have a volume that’s a billion times smaller.
Some say that black holes are more powerful than the Sun. Black holes are some of the most violent objects in the universe, with gravity strong enough to rip stars apart. The gravitational force of a black hole is so strong that nothing can escape its pull once it crosses the event horizon
The Sun is powerful, producing 400 trillion trillion watts per second, which is equivalent to detonating a trillion megaton nuclear warheads every second. However, the Sun is small compared to some other stars.
Black holes are so massive that some are 12 billion times more massive than the Sun. Black holes are also hotter than the Sun, with some shooting out X-ray jets that are 60,000 times hotter than the Sun
Yes, a black hole could potentially eat the Sun. This would have disastrous consequences for the planet and the rest of the solar system.
Astronomers have observed a supermassive black hole eating a sun-like star. The black hole started by devouring gas and dust from the inner disk. As this happened, matter from the outer disk filled in the gaps left behind.
If the Earth were to encounter a black hole, or have one get too close, the planet would be destroyed. However, this is an extremely unlikely scenario
According to NASA, if the Sun were to suddenly become a black hole with the same mass as it has today, the orbits of the planets would not be affected. This is because the gravitational influence on the solar system would remain the same
However, if a massive black hole were to come near our solar system, it would destroy everything nearby, including planets and light. If it were near the Sun, it would destroy the Sun, and nothing would be able to grow.
According to NASA, black holes do not go around in space eating stars, moons, and planets. Earth will not fall into a black hole because no black hole is close enough to the solar system for Earth to do that
Yes, the Sun orbits the black hole at the center of the Milky Way. The black hole is called Sagittarius A* and weighs 4.3 million Suns.
The Sun and the rest of our solar system also orbit the center of the Milky Way. The solar system moves at an average speed of 450,000 miles per hour (720,000 kilometers per hour). It takes 230 million years to complete one orbit around the Milky Way
So what will happen to the Sun? In some 6 billion years it will end up as a white dwarf— a small, dense remnant of a star that glows from leftover heat. The process will start about 5 billion years from now when the Sun begins to run out of fuel.
if the Sun collided with a small black hole, it would appear to go dark within eight minutes. The planets would continue to orbit the Sun, but the Earth would freeze and become uninhabitable.
According to NASA, if the Sun were replaced with a black hole of the same mass, the Earth’s orbit would remain unchanged. However, the Earth’s temperature would change, and there would be no solar wind or solar magnetic storms.
According to Astronomy Stack Exchange, the chances of a black hole coming anywhere near the Sun in the next billion years are very small
According to NASA, no black hole is close enough to the solar system for Earth to fall into it. However, some scientists believe there may be a black hole orbiting the Sun
Astronomers believe that supermassive black holes exist at the center of most large galaxies, including our own Milky Way. They can detect black holes by observing their effects on nearby stars and gas.
The black hole at the center of our galaxy is called Sagittarius A* and has a mass of 4.3 million Suns. Its shadow diameter is about half the size of Mercury’s orbit in our solar system.
The nearest known black hole is Gaia BH1, which was discovered in 2022 and is 1,560 light-years away from Earth.
