What does it mean when a star has a larger parallax than another star?

It means that its apparent movement - due to Earth's movement around the Sun - is greater, and that therefore the star is closer to us.

What are the advantages and disadvantages of measuring the parallax of a star from Pluto?
Advantage: A much larger orbit, thus, the parallax angle will be larger and easier to measure. Disadvantage: A full orbit of Pluto takes 248 years.
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.

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?
Parallax, take a measurement of where the star is at one time, take another at the exact opposite time, do a little trig and you have the distance.
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 apparent velocity of a star relative to another star?
It is the a parallax.
If a star's parallax is too small to measure does that mean that it is close or far from Earth?
Nearby stars have a larger parallax angle.

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.

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.
