Why would astronomers measure the parallax angle of a planet or star?
It's distance
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.
What do variable stars help astronomers measure?
Distance.
How do astronomers measure distance to the stars?
With a long measuring tape.
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.
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.
What planet some astronomers don't think is a planet?
Astronomers have decided that Pluto does not meet the definition of a planet.
What unit of distance do astronomers use to measure distances to stars?
Usually light-years, or parsecs.
What is used to find a planet's distance from the sun?
When exploring space, astronomers use astronomical units, (AU) to measure the distance from one object to another. Since every distance from one object in our solar system to another object in our solar system, the distance of a planet from the sun would be measured in astronomical units
Do astronomers think Pluto is a planet?
Astronomers think Pluto is a dwarf planet. And they're right.
How do astronomers measure it?
How do they measure what?
Do all astronomers think that Pluto is a planet?
No. It was categorised as a dwarf planet in 2006, but not all astronomers agree with that decision.
