What is the Schwarzschild radius of a black hole the mass of the Earth?
Accordingly, the Sun has a Schwarzschild radius of approximately 3.0 km (1.9 mi), whereas Earth’s is only about 9 mm (0.35 in) and the Moon’s is about 0.1 mm (0.0039 in)….Parameters.
| Object | Earth |
|---|---|
| Mass | 5.97×1024 kg |
| Schwarzschild radius | 8.87×10−3 m |
| Actual radius | 6.37×106 m |
| Schwarzschild density or | 2.04×1030 kg/m3 |
What should be the radius of a black hole if its mass is same as of earth?
A black hole with a Schwarzschild radius of about a centimeter, which would make it about the size of a coin, would have about the same mass as the Earth. The reason the Earth will be destroyed but not simply swallowed up is because the Earth will be resisting the black hole in at least two ways.
Can you measure the diameter of a black hole?
An international team of scientists working with the Event Horizon Telescope project have been able to measure the radius of a black hole for the first time. The radius of the black hole was observed with the Event Horizon Telescope – a chain of radio telescopes in Hawaii, Arizona, and California.
How do you find the mass and weight of an object?
Summary
- Weight is a measure of the force of gravity pulling down on an object. It depends on the object’s mass and the acceleration due to gravity, which is 9.8 m/s2 on Earth.
- The formula for calculating weight is F = m × 9.8 m/s2, where F is the object’s weight in Newtons (N) and m is the object’s mass in kilograms.
What is the equation of a black hole?
This phenomenon is thought to be the final fate of the more massive stars (see black hole). The Schwarzschild radius (Rg) of an object of mass M is given by the following formula, in which G is the universal gravitational constant and c is the speed of light: Rg = 2GM/c2.
How do you calculate the mass of a black hole?
Let’s look now at the black hole equation: g = G * M / r². The parameters of the black hole equation are: M Mass of the black hole. Typically a very big number, expressed in thousands of solar masses (at least). r Schwarzschild radius / event horizon / black hole radius.
What is the event horizon and gravity of a black hole?
Due to the nature of black holes, both the event horizon (also called Schwarzschild radius) and the black hole gravity at this point can be calculated from just the mass of the black hole. We will also explain below what is the Schwarzschild radius and what the black hole equation means.
What can I Calculate with the Schwarzschild radius calculator?
You can calculate anything, in any order. The Schwarzschild radius calculator lets you obtain the gravitational acceleration on the surface of a black hole, also called the event horizon.
What is the escape velocity of a black hole?
In the case of a black hole it is the point where the escape velocity is the same as the speed of light c. To learn more about escape velocity you can check the escape velocity calculator but put simply, it is the speed required to get away from the gravitational pull of an object.
