An object with gravity so strong nothing can escape is called?
a black hole.
Could you fly off of a planet because there is no gravity?
No. All planets have gravity. Any object massive enough to be considered a planet would have strong enough gravity that you could simply escape by jumping. It is, however, possible for an object to escape the gravity of any planet if it is launched in the right way and with enough speed.
What object is so dense that even light can not escape its gravity?
That is called a "black hole".
What is an object so massive that light cannot escape its gravity called?
A black hole
What is a massive and dense object from which light cannot escape its gravity called?
A "Singularity" or a "black hole".
Why planets do not move away through their orbit?
GRAVITY... gravity means that objects are "attracted" to other objects, and the larger the object, the more GRAVITY will "attract" the object. The sun's gravity is too large for the planets to overcome.
How much speed required to go against gravity?
Assuming there is no air resistance, if an object starts at a speed of 11.2 km/sec, it can escape the gravitational field of Earth. This "escape velocity" is different for different planets, moons, etc.Assuming there is no air resistance, if an object starts at a speed of 11.2 km/sec, it can escape the gravitational field of Earth.

How fast must an object go to leave a planets gravity?
The speed that ab object must travel at to escape a planet's gravity is called escape velocity. This value varies depending on the mass and diameter of the planet. Here are the escape volcities of the eight planets of our solar system. Mercury: 9,400 mph Venus: 23,000 mph Earth: 25,000 mph Mars: 11,000 mph Jupiter: 133,000 mph Saturn: 77,000 mph Uranus: 48,000 mph Neptune: 53,000 mph Note that escape velocity only takes gravity into account and ignores other forces. An object launched from Earth's surface or from any other planet with a substantial atmosphere at escape velocity would be quickly destroyed and slowed down by air resistance.
What object has such a strong surface gravity that light cannot escape?
A black hole
What would happen to an object in orbit around planets if the planets force of gravity were stronger than the objects inertia?
The object would crash into the planet.
Which object's gravity holds the planets in their orbits?
The sun's gravity holds the planets in their orbits. It also holds other space objects in their orbits, such as asteroids.
What is force of gravity on an object called?
That is called the object's weight.
