∙ 15y agoIt depends on the distance they are measuring. For things very very close in space they use kilometers. For things a bit farther away, like planets, they use Astronomical units (au). For things way out there, like stars, they use light-years.

∙ 14y agoThe formula you use to find that distance depends on whether the planet is closer to the sun than Earth (Inferior) or further than Earth (superior)

What is the most reliable method that astronomers use to estimate the distance to a galaxy?
The Parallax Method. See the link for more info.
What method do astronomers use to determine the distance to a relatively close star like Sirius?
For nearby stars, the parallax method is used.
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.
Who was the first astronomer to use parallax?
In 1838 Friedrich Bessel was able to measure the parallax of the nearby star 61 Cygni and thus determine its distance and independenly confirm the fact that the Earth orbits round the Sun.
How can be the distance between the sun and the earth measured?
To measure the distance from the earth to the sun, or to any star for that matter astronomers use a form of trigonometry called Parallax (see related Link). Simply put, think of measuring a known distance (the larger the better) and measure the angles to the sun at the same time at each end of that baseline. Using the Angle-Side-Angle formula, (See related link #2) the lengths of the other two sides can be calculated
What is used when astronomers measure the distance from the sun to the earth?
Parallax is the method that astronomers use to measure the distance from the sun to the earth.
How do astronomers measure the distance to nearby stars?
Astronomers use a method called parallax to measure the distance to nearby stars. Astronomers can measure parallax by measuring the position of a nearby star with respect to the distant stars behind it. Then, they measure the same stars again six months later when the Earth is on the opposite side of its orbit.
The method astronomers use to measure the distance to stars that are less than 1000 light years from earth?
The method called "parallax.
How do astronomers measure distances to stars including the parallax method?
They use the banana method
What is the most reliable method that astronomers use to estimate the distance to a galaxy?
The Parallax Method. See the link for more info.
How is a parallax helpful to astronomers?
Parallax is the apparent change in postion of an object when looked at from two different places. Astronomers use parallax to find how far away nearby stars are.
What method do astronomers use to determine the distance to a relatively close star like Sirius?
For nearby stars, the parallax method is used.
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.
How do astronomers measure the distance of planet?
They use complicated trigonometry and mathematics.
What unit of distance do astronomers use to measure distances to stars?
Usually light-years, or parsecs.
How do astonomers measure the distance to nearby stars?
Astronomers use the unit of measure "Light Years" to calculate the distance between pretty much anything in the Universe.
Who was the first astronomer to use parallax?
In 1838 Friedrich Bessel was able to measure the parallax of the nearby star 61 Cygni and thus determine its distance and independenly confirm the fact that the Earth orbits round the Sun.
