The sun is the only star we know of whose planetary system definitely includes
one with life on it. Other than that, and the fact that it's much closer to us, there is
absolutely nothing out of the oridinary about our sun, compared to billions of other
main-sequence stars.
It isn't different. The sun is hotter and brighter than the average main sequence stars, but it is within what is considered normal. There is nothing extraordinary about the sun itself.
There are billions of stars that are not on the main sequence.
It can have many different sizes. Only the largest giants are no longer main sequence stars.
The smallest stars in the main sequence are the stars with cooler surface temperatures.
"main sequence" is the tern.
main sequence stars , our sun is also a main sequence star
No. They have the lowest temperatures on the main sequence. The hottest main sequence stars are blue.
The main sequence is a map of star brightness against their temperature. Stars that lie on the main sequence in the top left are the high mass stars. Cooler, smaller stars lie near the line at the lower right.
Main sequence stars.
Main sequence stars are found in all galaxies.
Main Sequence
About 90% of all stars are main sequence stars, including our Sun. These stars are in the stable phase of their lifecycle, where they fuse hydrogen into helium in their cores. Main sequence stars are the most common type of stars found in the universe.
