The stars are always there, it just doesnt seem like it when there are many city lights, or if its a cloudy night.
Stars live for various lengths of time mostly dependent on their size. Small stars live longer (up to many tens of billion years). Large stars live short lives (comparatively) only shining for a few hundred million or a billion years.
If you refer to the diameter, a neutron is tiny - only 20-30 kilometers in diameter. In comparison, main sequence stars have a diameter of at least several hundred thousand kilometers.
Most of its active life, usually. The actual time may vary from only a few million years (for very massive stars) to trillions of years (for some red dwarves).
We only name things that we can see, or detect. The first stars in the universe were likely supergiant stars that exploded in supernova explosions within a few hundred million years. The material blasted into space by the first three or four generations of rapidly-dying stars provided the raw material that came together to form our solar system.
Over 100 billion just in ourgalaxy. So more than 100 billion stars in a galaxy!
Only a few. Sometimes only one.
As many as stars in the sky!!! But only a few are professional photographers who can capture quality photos.
Hypergiants are relatively rare. Only a few stars become hypergiants, and they don't last very long (only a few million years). Probably a few in every major galaxy.
A few!
sometimes only a few days. a species of mayfly only live a few minutes
No count of stars in any galaxy has been made. Estimates are given.Galaxies can contain as little as a few million stars or as many as trillions.NGC 1427A. A few billion maybe.
A dwarf galaxy can have a few million stars; a huge galaxy can have a trillion stars or more.
None. Our solar system is one of those rare few with only one star.
No. Many stars have a distinctly reddish hue, and a few are a little bit blue.
Many had tried but only a few had survived.Or:Many had tried but few had survived.
Yes. There are only a few thousand stars that are visible to the unaided eye. All of them are in one small portion of our galaxy, which contains an estimated 200 billion stars. Beyond that there are an estimated 100 billion galaxies in the known universe, most of which have billions of stars of their own. Many of the stars have planets orbiting them.
An average dwarf galaxy contains few as ten million (107) stars.
