How do astronomers know that the sun has a finite lifespan?
DiamondXmas
For a start, the Sun emits energy; the laws of Thermodynamics state that that can't go on forever. Beyond that, astronomers know quite a deal about what goes on in stars such as the Sun; specifically, hydrogen is converted to helium, in a process known as fusion. After a while (a few billion years in a star with the mass of our Sun), the star will run out of its fuel (the hydrogen). Helium can then be converted to heavier elements, but this doesn't last forever, either.

What is the average distance from earth to the sun for astronomers?

How do astronomers observe the sun at different wavelengths?
Cus they is BOSS
What did the Indian astronomers know about the solar system including the sun?
Indian astronomers had extensive knowledge about the solar system, including the sun. They knew that the sun is a star and not a deity, and they accurately calculated its distance from the Earth. They also understood the nature of solar eclipses and had developed methods to predict their occurrence. Additionally, they made observations regarding the movement and positions of planets within the solar system.

How do astronomers know what goes on in the interior of the Sun?

How long do astronomers estimate the sun will last before it begins to die?
Astronomers think the sun will die in 2012
How do astronomers know what condition exist inside the sun?
While it is difficult to know exactly what is going on inside the sun, scientists make educated guesses. They have radio and optical telescopes and other instruments monitoring the sun all the time.
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 observation about the sun's motion did early astronomers use to supportnthe geo centric theory?
GEOCENTRIC THEORY You already know as a fact that the Earth and all solar system bodies orbit the Sun but for centuries astronomers believed that the Sun and planets orbited the Earth. To us it looks natural.
Is sunshine limitless?
No. 1) the sun puts out a finite amount of energy. 2) the sun has a finite life-time. (about another 5 billion years).
