Question

5 point

Answer 1

All stars are round, and there are many trillions of stars, although you can only see about 3,000 of them at any one time without a telescope. The sun is a typical star, only much closer than all the others.

Answer 2

Hi. From the web, "star (stär)

(astronomy) A celestial body consisting of a large, self-luminous mass of hot gas held together by its own gravity; the sun is a typical star.
(mathematics) For a member S of a family of sets, the collection of all sets in the family that contain S as a subset.
(nucleonics) A star-shaped group of tracks made by ionizing particles originating at a common point in a nuclear emulsion, cloud chamber, or bubble chamber; some stars are produced by successive disintegrations of an atom in a radioactive series, and others by nuclear reactions of the spallation type, such as those due to cosmic-ray particles. Also known as nuclear star.
(optics) A light source that subtends a very small angle at the entrance pupil of an optical instrument and is used to test the instrument."

So, four.

Answer 3

Carl Sagan said that there are as many stars in the visible universe as there are grains of sand on every beach in the world.

But basically, you can get an idea if you consider that there are hundreds of billions of stars in a galaxy, and that there are hundreds of billions of galaxies.

Multiply those numbers together and you get the idea.

Answer 4

Well... since it is how many star are their (thier)... I would say there is only one.

Now if we were talking stars there could be a lot more.

Answer 5

billions....many will never be found....they are only just learning the extent of the size of the universe
the sun is a star....it is hundreds of thousands times bigger than the earth
