The size of a quasar can be inferred from the timescale of variations in its light output.
Assuming that no signal can travel across the source faster than the speed of light, the
time scale of the fastest variations sets an upper limit on the size of the quasar (i.e., size quals approximately the variation timescale times speed of light).
An alternative method called 'reverberation mapping' monitors changes in the quasar's light output, then looks for these same changes in the light output from specific spectral lines. The delay times the speed of light gives the size of the quasar.

Can 8 earth's fit in the black hole?
yes and no depends on size of hole :]
How can the mass of a black hole can be measured?
The mass of a black hole can be measured by observing the orbits of objects around it, such as stars or gas clouds. By studying the gravitational effects of the black hole on these objects, astronomers can calculate its mass. Another method is to measure the distortion of light from objects behind the black hole, known as gravitational lensing, which can provide information about the black hole's mass.
Does a medium size star become black holes?
The size of a black hole, as defined by the size of the event horizon, depends on the mass of the black hole and its electrical charge. The diameter of the event horizon is directly proportional to the black hole's mass. Adding electrical charge decreases the size of the event horizon.
How big would the sun be if it was a black hole?
Firstly our sun is too small to become a black hole. Only stars that are a million to a billion times our sun do this, because they burn through their fuel quickly, unlike our sun. A typical black hole has 3 times the mass of our sun
What would happen if two black hole were to merge into each other?
You would have a black hole the size of the combined mass of the two black holes.
How big is a black hole and what factors determine its size?
A black hole's size is determined by its mass, which is the amount of matter it contains. The more mass a black hole has, the larger its size. The size of a black hole is typically measured by its event horizon, which is the point of no return where gravity is so strong that not even light can escape. The event horizon's size is directly related to the mass of the black hole.
What happens after entering a black hole?
Any matter that enters the black hole will be destroyed. Also, it will increase the black hole's size.
Can a black hole get to the size of a planet?
A black hole can definitely get to the size of a planet. The width of the largest known supermassive black hole is thought to be over ten times the size of the entire orbit of Neptune around our Sun.
Is there a maximum size limit to a black hole?
No.

What is the size of a black hole and how does it affect its gravitational pull?
The size of a black hole is determined by its mass, with smaller black holes having a smaller size. The gravitational pull of a black hole is incredibly strong due to its mass being concentrated in a very small space, creating a powerful gravitational force that can even trap light.
What is the minimum and maximum size of the black hole?
There isn't one. It depends on how much matter the collapsed star (black hole) has gathered.
Is an Intermediate-mass black hole a type of black hole?
Yes. Intermediate-mass blackhole is a medium size black hole. Scientists have found stellar black holes and supermassive black holes but there is no prove that Intermediate-mass black type of black holes exist. My opinion is that they do exist because when a black hole is becoming a black hole supermassiveblack hole it will need to go though this stage of intermediate-mass black hole.
