Distance to nearby stars can be determined from?
stellar parallax
Why were early astronomers unable to detect stellar parallax?
Pressumably, they didn't have the high-precision devices required to measure those angles. You must consider that we are talking about extremely small angles - even the closest star has a parallax of less than one arc-second (1/3600 of a degree).
What does stellar parallax prove?
Heliocentrism.
The apparent shift in the position of nearby stars when compared to distant stars is?
Doug Fany answer: Parallax
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.

What measures star distance from the Earth?
Stellar Parallax Astronomers estimate the distance of nearby objects in space by using a method called stellar parallax, or trigonometric parallax. Simply put, they measure a star's apparent movement against the background of more distant stars as Earth revolves around the sun.

What have astronomers discovered by measuring small gravitational wobbles in stars?
They have discovered planets and other large bodies in alien star systems by measuring stellar wobbles.
What was not seen telescopically by galileo?
Stellar Parallax
Stellar parallax is NOT a type of triangulation technique?
True
What can distances to nearby stars determined by?
Stellar parallax
Who discovered stellar parallax?
Friedrich Wilhelm Bessel was the first person to find the parallax of a fixed star.
The apparent shift in the position of nearby stars when compared to distant stars is?
Doug Fany answer: Parallax
What is the cause of stellar parallax?
Earth's orbit around the Sun.
Do scientists use stellar parallax to determine a star's temperature?
Not if they have the faintest clue what they're doing. Parallax is used to measure distance, not temperature.
