The distance between the 'left' and 'right' eyes when measuring stellar parallaxes?
The Earth's orbit - diameter about 300 million km. - is used for this purpose. In other words, the position of a star (compared to objects that are further away) is measured when Earth is at one side of its orbit, and then again 6 months later, when Earth is at the opposite side of its orbit.

Distance to nearby stars can be determined from?
Distance to nearby stars can be determined using the method of trigonometric parallax, which involves measuring the apparent shift in position of a star relative to more distant stars as the Earth orbits the Sun. This shift allows astronomers to calculate the distance to the star based on the angle subtended by the Earth's orbit.
How Can the observation of stellar parallaxes in general be used as evidence against a geocentric view of the cosmos?
The observation of stellar parallaxes is evidence against a geocentric view of the cosmos because parallax shifts in the positions of stars as observed from Earth would not occur if the Earth were at the center of the universe. The fact that we can observe parallax in stars from different positions on Earth supports the heliocentric model, where Earth revolves around the Sun and is not at the center of the cosmos.
The apparent shift in the position of nearby stars when compared to distant stars is?
called stellar parallax, and it is used to measure the distance to nearby stars. This apparent shift occurs due to the Earth's orbit around the Sun, which causes our viewpoint to change over time. By measuring the angle of the shift, astronomers can calculate the distance to the star.
It is a unit of stellar distance?
Since you've not provided any clues... It could be - ight year, parsec or astronomical unit
What do astronomers use as a baseline in measuring stellar parallax?
Is it Jupiter's orbit, a parsec, the average diameter of the Earth's orbit or a light year? Please choose one of the following.
What has the author Louise F Jenkins written?

What is a stellar unit?
A stellar unit refers to a unit of distance used in astronomy to measure the distance between stars. It is typically equivalent to the mean distance between stars within a galaxy, which can vary depending on the galaxy being observed.
What units are stellar distances expressed in?
Stellar distances are measured in light-years, which is the average distance between the Earth and the Sun.
Stellar distance are usually expressed in what units?
A light year

Is triangulation a trustworthy method of measuring stellar distances regardless of the distance?
false, too much margin of error to have precise angles
Why are eclipsing binaries so important to measuring the masses of stars?
Eclipsing binaries are crucial for measuring stellar masses because they allow astronomers to determine the stars' orbital parameters through observed changes in brightness as one star passes in front of the other. By applying Kepler's laws of motion and Newton's law of gravitation, the mass of each star can be calculated with high precision based on the orbital period and the distance between the stars. This direct measurement of mass is essential for testing theoretical models of stellar evolution and understanding the properties of stars across various stages of their life cycles.
What is the most accurate way to determine the distance to a nearby star?
The most accurate way to determine the distance to a nearby star is through parallax measurement. This method involves observing the star's apparent shift in position against background stars as the Earth orbits the Sun. By measuring this shift, astronomers can calculate the star's distance based on trigonometry.
