The star Sirius is known to be 8.6 light years away What is the parallax angle?
The parallax is 379.21 mas (Minute of arc) [See related link] or 2.64 parsecs [See related link]
Is a star with no measurable parallax is very close to Earth.?
No, if you can measure no parallax, the star is far away - further than a certain distance.
How is the distance measured of stars less than 1000 light years away?
The parallax method is usually used in this case. Earth's movement in its orbit cause an apparent shift in position in such a star.
What do you understand by the statement a star is eight light years away from the earth?
The light from a star eight light years away will take eight years to reach Earth.
Is a star with no parralex very close to earth?
No. A star with no visible parallax is far away.
If a star has a parallax of 0.05 then its distance in light years is about?
If a star has a parallax of 0.05 (seconds of arc) then its distance in light years is about 65.2 light years. A little more detail, if required: Distance to a star (in parsecs) = 1/parallax (in seconds of arc). So, in this case: Distance = 1/0.05 = 20 parsecs. A parsec is a distance of about 3.26 light years. So, that means the answer is about 20 x 3.26 light years. That's about 65.2 light years.

If a star has a parallax of 0.20 arc seconds what is the distance to that star?
I assume you mean the parallax. If the parallax is 0.1 arc-seconds, then the distance is 1 / 0.1 = 10 parsecs.I assume you mean the parallax. If the parallax is 0.1 arc-seconds, then the distance is 1 / 0.1 = 10 parsecs.I assume you mean the parallax.

If Vega is 25.3 light year from earth and arcturus is 36.7 light years away which star would have a greater parallax explain?
vega its like a triangle the farther away one part is(arcturis) the narower the triangle is (paralax)
Is a star with no measurable parallax is very close to Earth.?
No, if you can measure no parallax, the star is far away - further than a certain distance.
What star is 4.5 light years away?
Probably you mean Alpha Centauri. That star is about 4.4 light years away.
How is the distance measured of stars less than 1000 light years away?
The parallax method is usually used in this case. Earth's movement in its orbit cause an apparent shift in position in such a star.

The light from a star eight light years away will take eight years to reach Earth.
How or with what do people measure a light year?
This can't be measured directly (as in, applying a measuring stick), so the distances are calculated in other ways. Several methods are used; for a start, for nearby stars, the star's parallax is measured. The smaller the parallax, the farther away the star is. Parallax is the apparent change in position, of a star, compared to the far-away background, as Earth moves from one side of its orbit, to the other.This can't be measured directly (as in, applying a measuring stick), so the distances are calculated in other ways.

A measure of amounts of light received on earth is a star's what?
Parallax
What star is 8.6 light years away?
Sirius is about 8.6 light years away from us.
Is a star with no parralex very close to earth?
No. A star with no visible parallax is far away.
