If one star has a parallax ten times larger than another's the first star is?
The first star is closer to the earth than the second. The exact distances will depend on how large the angles are and also how far the star is away from the perpendicular to the earth's ecliptic. In any case, the distances will depend on trigonometric ratios and the distance to the first star will not be one tenth the distance unless the angles are very small.
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 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.
Which star would have a greater parallax the earth or the arcturus?
Earth isn't a star and doesn't (can't) have a parallax, becuse we use Earth's orbit as a baseline to measure parallax.
The most basic way to measure the distance to a star is?
The most basic way to measure the distance to a star is through parallax. This involves observing the shift in the star's position as seen from different points in Earth's orbit, allowing astronomers to calculate the star's distance based on its apparent movement.
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 would have a greater parallax due to its closer distance to Earth compared to Arcturus. Parallax is the apparent shift in position of an object when viewed from different perspectives, and the nearer an object is to the observer, the larger its parallax.
Is parallax a star?
The parallax refers to the apparent change in the star's position, due to Earth's movement around the Sun. This parallax can be used to measure the distance to nearby stars (the closer the star, the larger will its parallax be).
What does a big parralax say about a stars distance?
The larger a star's parallax, the closer the star is to us.

What is the parallax angle of rigel kentaurus?
It is 754.81 milliarcseconds. Also, the star is Rigil Kentaurus, not Rigel which is the name of another star.

If a star's parallax is too small to measure does that mean that it is close or far from Earth?
If a star's parallax is too small to measure, it means that the star is far from Earth. Parallax measurements are used to determine the distance of nearby stars by observing their apparent shift in position as Earth orbits the Sun. Stars with large parallaxes are closer to Earth, while stars with small or undetectable parallaxes are further away.
Which star would have a greater parallax the earth or the arcturus?
Earth isn't a star and doesn't (can't) have a parallax, becuse we use Earth's orbit as a baseline to measure parallax.
What can parallax be used to determine about a star?
Parallax is a method used to find the distances of stars.
Parallax can't be used on a star if the star is too?
Close.
How do scientists determine the parallax of a star?
they look at the star in, say, spring, then fall or summer then winter. we have to be on opposite sides of the star to see the parallax, so it takes about a year
What is a stars parallax?
The parallax refers to the apparent change in the star's position, due to Earth's movement around the Sun. This parallax can be used to measure the distance to nearby stars (the closer the star, the larger will its parallax be).
What two words are the abridgement for a parsec?
parallax second When we observe a star from opposite ends of the Earth's orbit, if there is a parallax difference of 1 arc second, that star is 1 parsec away.
