Are you asking if there is a minimum velocity to escape the gravitational pull of an asteroid?

The answer is yes.

The second part is more difficult as it is variable, based upon the mass, size, and shape of the asteroid and where you start from.

Assuming that the asteroid has no atmosphere, the necessary velocity would be roughly the square root of... double the universal gravitational constant, times the mass of the asteroid..., divided by the distance from the center of gravity.

What is the escape velocity of the asteroid belt?

Each asteroid has its own escape velocity.


What is the escape velocity from an asteroid with mass 3000 gm and radius of 10 m?

The escape velocity from an asteroid can be calculated using the formula: escape velocity = sqrt(2 * gravitational constant * mass of asteroid / radius of asteroid). Substituting the given values, the escape velocity from the asteroid would be approximately 200 m/s.

Is the escape velocity from the center of the earth different from the escape velocity from Earth's orbit?

Yes, very much so.


Can an intercontinental ballistic missile reach escape velocity?

Yes. Probes have already be sent to the Moon, and other planets; this requires a velocity very near the escape velocity from Earth. Other probes are leaving the Solar System, so they achieved the much higher escape velocity required to escape the attraction from the Sun.


The escape speed from a very small asteroid is only 24 If you throw a rock away from the asteroid at a speed of 32 what will be its final speed?

The final speed of the rock will be 32 m/s. The escape speed of the asteroid does not affect the speed of the rock once it has been propelled away from the asteroid. The initial velocity of the rock allows it to overcome the gravitational pull of the asteroid and achieve a final speed of 32 m/s.


There is no atmosphere on the moon. Explain on the basis of escape velocity?

The moon's escape velocity is lower than the average velocity of gas particles in its atmosphere, so the moon cannot retain an atmosphere as the gas particles would escape into space. This is why the moon has no significant atmosphere.


Is escape velocity of light infinity?

Not at all. It would take an infinitely large mass to produce an infinite escape velocity, and no such infinite mass exists. Furthermore, the escape velocity for any object is the same no matter what is trying to escape, so light does not have its own escape velocity. This question presumably concerns black holes. Light does not escape from black holes because the escape velocity is greater than the speed of light. The speed of light is not infinite, it is 300,000 kilometers per second.


What is the difference between escape velocity and orbital velocity?

Escape velocity is the velocity that an object needs in order to reach infinite distance, wherein the force will equal to zero. Orbital velocity is the velocity of an object so it can stay in orbit.
