How long does it take light to reach earth from Betelgeuse?
Betelgeuse is a red supergiant star about 640 light-years from Earth. So light from Betelgeuse takes 640 years to get here. Here's an interesting fact; the star Betelgeuse is probably near the end of its life, and may explode in a supernova explosion any time. Very massive stars like Betelgeuse live fast and die in under 100 million years, and Betelgeuse will probably go supernova within the next 10,000 years. This is like no time at all in cosmic terms, but in terms of a HUMAN lifetime, it probably will NOT happen while we're alive to see it. But it could. In fact, Betelgeuse might have exploded 500 years ago, and we wouldn't know it for another 140 years!
How big is the Sun as compared to Saturn?
The gas giant's diameter is 120,034 km while the sun's is 1,377,648 km. this means that you could fit 11 of them (Not counting the rings) into the diameter of the sun and you would have room for 40% of another one left over. In terms of surface area, the Sun is 133 times larger than Saturn.
Astronomy.what is the name of the third largest star?
In terms of diameter 'VV Cephei A' probably holds this position.
Is the sirius star 10 times bigger then the sun?
No. In terms of diameter Sirius is 1.7 times the size of the sun.
How long before you see Betelgeuse explode?
It is impossible to say when it will explode. It seems very unstable and many astronomers think it may be soon. But soon in astronomical terms could be a million years from now, or it could happen next week.
Rigel aldebaran Sirius Antares KY cygni betelgeuse pollux arrange in ascending order?
In terms of size from smallest to largest, its Sirius, Pollux, Aldebaran, Rigel, Betelgeuse, Antares, and KY Cygni.
Temperature of Rigel?
There is more than one star in the Rigel "system". The main star, in terms of brightness, is Rigel A. That has a surface temperature of about 12,000 degrees Celsius.
Are the sun and earth the same size?
No, not even close. In terms of mass, the Sun is about 332,946 times as massive. In terms of volume, the Sun is about 1,300,000 times larger. In terms of diameter, the Sun is about 109 times as wide.
What is diameter in terms of radius?
diameter = 2 x radius

What is the area of the circle in terms of pie with a diameter of 36?
The area of a circle, in terms of pie, with a diameter of 36 is: about 324pi
How many time is the sun larger than the moon?
In terms of diameter, the Sun is 400 times the Moon's diameter. It is also 400 times as far away and this means that the disk of the moon and the sun appear the same size when viewed from earth.
If the diameter of a circle is 40 m then what is the area in terms of pi?
If the diameter of a circle is 40 m then the area (in terms of Pi) is: about 400pi m2
What does diameter mean in math terms?
A line that bisects a circle and goes through the center of it is the diameter.
How big is earth from the size of the moon?
The moons diameter is approximately 25 % the size of earth. So the Earth is approximately 4 times the diameter of the moon. That really doesn't do justice to how much larger the Earth actually is however since increasing the diameter by 4 increases the overall landmass by substantially more than this. In relative terms the surface area of the moon if laid out flat is slightly larger than the land mass of the continent of Africa.
Do cubes have a diameter?
In basic terms...no. A diameter only applies to circles or spheres. The diameter is the distance across the middle at the widest point and the radius is half of the diameter.
