How can two supergiant stars have an absolute magnitude of -3 but one has a radius of 10 times the sun and the other 100 times the sun?
The absolute magnitude of a star depends on the size and temperature; a large cooler star can generate as much light as a small very hot star.
Can you give an example of a hot star which is not very bright?
White dwarf stars are hot , but not very bright, because they are so small. An example is "Sirius B", the companion of "Sirius A", the brightest star in the sky.
How can you be certain that white dwarfs are very small?
The small size can be deduced from the small amount of light they emit. A "normal" star of the same color (and therefore temperature) emits thousands of times more light.
What star's are small?
hello im tess i think little stars are called anphebeansh
Does a shooting star emit light of its own?
yes. the shooting star emits lots of light ************* A shooting star (meteor) is dust or very small bits of rock that enter the earth's atmosphere at a very high speed. The friction of the air heats the shooting star so hot that in incandesces (glows)- so yes, it does give off it's own light.
Do stars that are very hot and very dim have a small mass or a small radius?
stars that are dim probably have both a small mass and a larger radius.
What star is very small?
dwarf star
The birth of a small star and a very massive star are the same but the end of their life is very different Describe the difference in the fate of a small star and a very massive star?
The difference between the death of a small star and a massive star is what the become afterwards. A small star will typically become a red dwarf while a large star will become a neutron star or a black hole.

For very small angles the focal length of a concave mirror is?
Half of the radius
What kind of star is Van Maanen's?
a very strange but intesting star :p
What kind of star can be detected by radio telescopes?
Radio telescopes detect stars known as 'Pulsars'. They're very small and also known as neutron stars.
Why is there only gravity in black hole and not anywhere else in space?
Its simple friends, the space doesn't have mass or its negligible in sense but the black hole is the result of the life ending of a star and thus its mass is also very very high and its radius is also very very low. Black holes are very small in size having very large mass. so as we know gravity is directly proportional to the mass but it is indirectly proportional to the radius and i think you got the answer
Does the star enter the moon?
Stars and the moon are very very far away. the closest star is over 20 light years away. and, the moon is very very small compared to a star. so a star couldent enter the moon, the moon would enter a star.
What is a tiny point that is very bright small far away?
a star
Why is a sun a star?
the sun has always been a star even before it was called the sun. In fact the sun is a very very small star compared to all the other stars in the universe
What is the summary of the short story the star?
i ise sun is a small or ordary star just very close to earth
