What else can I help you with?
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 a massive and dense object from which light cannot escape its gravity called?
A "Singularity" or a "black hole".
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 is an object so massive that light cannot escape its gravity called?
A black hole is an object so massive that light cannot escape its gravity, due to the intense gravitational pull caused by its mass and density.
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.
An object with gravity so strong nothing can escape?
An object with gravity so strong that nothing can escape is called a black hole. These regions of spacetime have such intense gravitational force that they trap even light, which is why they appear "black" or invisible to outside observers.
What object has such a strong surface gravity that light cannot escape?
A black hole
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.

An object with gravity so strong nothing can escape is called?
A black hole. It is a region of spacetime where gravity is so intense that nothing, not even light, can escape its pull once it crosses the event horizon.
Why are the planets called satellites of the sun?
They are natural satellites of the sun. A satellite an object that orbits another object , for a example the moon would be a natural satellite to earth. That is why planets are satellites, they orbit the sun.
The amount og gravity pulling on an object is called?
The amount of gravity pulling on an object is called weight. Weight is the force exerted by gravity on an object's mass.
