Well there is no another name that describes an Event horizon but you can call it "The point of no return" ( acc. to layman's term) i.e. the point at which the gravitational pull becomes so great that even light can't escape from it . It is the boundary in spacetime beyond which events can't effect an outside observer .
What else can I help you with?
What is the name given to material orbiting the event of a black hole?
Event horizon, not event - and it's called the accretion disk.
Can a super heated quasar escape a black hole?
No, a superheated quasar cannot escape a black hole. Quasars are extremely bright and energetic sources powered by accretion onto supermassive black holes, and their emissions arise from the material falling into the black hole. Once matter crosses the event horizon – the point of no return – it cannot escape the black hole, including the energy emitted by the quasar.
Why wouldn't an accretion disk orbiting a giant star get as hot as an accretion disk orbiting a compact object?
An accretion disk is heated by friction and compression, both of which are greater for material falling into a compact object as the material is forced into a smaller space. The hottest accretion disks would be found around black holes.
Can a planet orbit a black hole and why?
Yes, a planet could orbit a black hole, just like it could orbit a star. Gravity would bind them together. A planet orbiting 93 million miles from the sun feels exactly the same as if it were orbiting 93 million miles away from a black hole with the same mass as the sun has.
What is the shape of black hole?
The event horizon of a black hole is spherical.
What is the name given to material orbiting the event of a black hole?

What is the brilliant light coming from a black hole?
if there is light surrounding a black hole it is normally from material entering into the event horizon of the black hole.
Can a super heated quasar escape a black hole?
No, a superheated quasar cannot escape a black hole. Quasars are extremely bright and energetic sources powered by accretion onto supermassive black holes, and their emissions arise from the material falling into the black hole. Once matter crosses the event horizon – the point of no return – it cannot escape the black hole, including the energy emitted by the quasar.
Can a black hole become full?
No. When matter falls into a black hole it simply increases the black hole's mass, giving it stronger gravity and a larger event horizon.
Why wouldn't an accretion disk orbiting a giant star get as hot as an accretion disk orbiting a compact object?
An accretion disk is heated by friction and compression, both of which are greater for material falling into a compact object as the material is forced into a smaller space. The hottest accretion disks would be found around black holes.
What horizon is formed first?
The apparent horizon is formed first in the evolution of a black hole. It represents the point from which no light can escape, defining the boundary of a black hole's event horizon.
Can a planet orbit a black hole and why?
Yes, a planet could orbit a black hole, just like it could orbit a star. Gravity would bind them together. A planet orbiting 93 million miles from the sun feels exactly the same as if it were orbiting 93 million miles away from a black hole with the same mass as the sun has.
What would happen if a neutron star was near to a black hole?
It would all depend on how close the neutron star was. If it was outside the event horizon, then if would be observed to be orbiting "nothing". If it strayed too close to the black hole, then it would be slowly ripped apart, until a slightly larger black hole was all that is left.
What planet has a event horizon?
No planet has an event horizon. A black hole has an event horizon; it is the radius within which light cannot escape.
Is the sun orbiting a black hole?
No, the sun is not orbiting a black hole. The sun is part of the Milky Way galaxy and orbits around the center of the galaxy, where there is a supermassive black hole called Sagittarius A.
What is the shape of black hole?
The event horizon of a black hole is spherical.
Does a black hole have an horizon?
The so-called "event horizon" of a black hole is the point-of-no-return. That means that anything that gets inside the event horizon can't get out any more, even if if it moves at the speed of light.
