Which of these have an event horizon giant black hole white dwarf neutron star?
A black hole has an event horizon, beyond which nothing can escape, including light. Neutron stars also have an event horizon, called the "surface" or "crust," which marks the boundary within which matter is crushed by extreme gravity. White dwarfs, being less massive, do not have an event horizon.
Does a giant star have an event horizon?
No. An event horizon is an area where even light cant escape so only black holes have it
Is the event horizon mark the boundary which the density is roughly the same as that of the atomic nucleus?
The event horizon is not related to density comparison with the atomic nucleus. It is the point around a black hole where the escape velocity is equal to the speed of light, and nothing, not even light, can escape. The density of a black hole is concentrated in its singularity at the center, not at the event horizon.
Was the first neutron star observed in a supernova remnant?
Yes, the first neutron star was observed in a supernova remnant. The object, named PSR B1919+21, was discovered in 1967 in the Crab Nebula, the remnant of a supernova that exploded in the year 1054 AD.
How does a neutron star differ from a main sequence star?
A neutron star is a stellar remnant
Does neutron star have an event horizon?
No, they do not.

Is a neutron star or a black hole bigger?
A black hole has more mass than a neutron star, but if you are comparing volume it would depend on the mass of the black hole. A neutron star is estimated to be about 14 miles in diameter, which is larger than the event horizon of a black hole up to about 3.8 times the mass of the sun. A more massive black hole will be larger.
Does a giant have an event horizon?
If you mean a giant star, no.
Does a giant star have an event horizon?

What star has an event horizon?
That refers to a black hole - but a black hole is not exactly a star.

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 is bigger a black hole or a neutron star?
It all relates to what you define as big. A black hole is an infinite region in space with an infinite density. It's "event horizon" is not infinite. If you wish to categorise between size of a neutron star and a black hole's "event horizon", then a black hole is, in most cases larger - but there are micro black holes, which exhibit all the characteristics of a black hole but have a much smaller "event horizon". In the physical sense, everything is bigger than a black hole, but in a terminological sense (the event horizon) it would depend on the mass of the black hole.
What is a single point where all matter from an extremely massive neutron star has condensed and from which no light can escape?
A black hole is a single point where all matter from an extremely massive neutron star has condensed to a point of infinite density, called a singularity. The immense gravitational pull of a black hole is so strong that not even light can escape its event horizon, the point of no return.
Why does the companion star wrap around the nuetron star?
The extreme gravitational field of the neutron star...an object with typically 4 to 8 times the mass of our sun, packed into a diameter of about eight miles...pulls mass off of any close companion star, which spirals into the neutron star. If the companion star is close enough, it may over time totally disintegrate and be consumed by the neutron star, which itself may become massive enough to finally become a stellar "black hole", an object whose surface escape velocity would be greater than the speed of light, so that nothing, not even light, can escape beyond its "event horizon".
What is a sentence for neutron star?
Good sentence for neutron star - WOW ! see that;s a neutron star !!
