How do scientist weigh a star such as the sun?

Answer 1

It cannot. weight is a measurement of gravity between two objects. For example if I weigh 60 N on earth I would weigh around 10 N on the moon.

What you probably meant was how can the suns mass be measured; this can be done by taking the density multiplied by size.

Answer 2

A mass produces gravitation. The Sun attracts the planets, keeping them in their orbit. The things that need to be figured out for the calculation are:

• The gravitational constant. This can be measured in labs on Earth, for example, with a Cavendish balance (torsion balance).
• The distance from a planet to the Sun.
• Some details of said planet's orbit.
  

Answer 3

Scientists can weigh a star like the Sun by studying its motion in a binary system, where it orbits another star. By analyzing the orbital dynamics and applying Newton's laws of motion, scientists can calculate the masses of both stars. Additionally, the Sun's mass can be determined through the study of its gravitational effects on planets and other celestial bodies in the solar system.

Answer 4

One can know the mass of the Sun by measuring the distance and velocity of a planet orbiting the Sun.

Answer 5

A barometer can be used to measure the weight of air.
