Gravity causes the motions of planets, stars, and galaxies. It's why the Moon orbits around the Earth, and the Earth orbits around the Sun, and the solar system orbits around the galaxy.
I would, but what is the question?
When you kick a ball the when your foot hits the ball the force from your foot is now on the ball and if the ball bumps into somoene they might fall(if you kick hard)
When using parallax, astronomers calculate distance from the sun and not earth to improve on the accuracy of their measurement, since parallax angle decreases as star distance increases.
<h3>
What is parallax distance?</h3>
Parallax enables astronomers to measure the distances of far away stars by using trigonometry.
<h3>Why does astronomers measure parallax distance from sun?</h3>
As the distance of star increases, the parallax angle decreases, and great degree of accuracy is required for its measurement.
So taking a refence from the earth instead of the sun will impact the accuracy of their measurement.
Thus, when using parallax, astronomers calculate distance from the sun and not earth to improve on the accuracy of their measurement, since parallax angle decreases as star distance increases.
