Did astronomers believe that the sun was part of earth?
No.
Do volcanoes only erupt on earth?
No, Astronomers have discovered erupting volcanoes on Venus as well as Earth
Why would astronomers measure the parallax angle of a planet or star?
Astronomers measure the parallax angle of a planet or star to determine its distance from Earth. By observing the apparent shift in position of the object against the background stars as the Earth orbits the Sun, astronomers can calculate the angle and use it to estimate the object's distance.
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.
Why was it difficult for ancient astronomers to explain about the apparent retrograde motion?
If, as ancient astronomers thought, that our Earth was the center point of rotation for other planets, then it is difficult to explain why those planets would move in a direction opposite to their rotation. Ptolemy came up with a solution that worked, but it was a cumbersome one. Nicolae Copernicus was able to show that this retrograde motion could be explained easily if it were assumed that our Sun was the actual center of rotation of the planets.
What did Indian astronomers recognize about earth?
Indian astronomers recognized that the Earth is a sphere and that it revolves around the Sun. They also accurately calculated the Earth's circumference and understood the Earth's axial tilt, leading to the development of the concept of seasons.

What year was Jupiter discoverded?
Because a telescope is not needed to see Jupiter from Earth, ancient astronomers were aware of its existence.
What did ancient astronomers know about the earth?
Ancient Greeks such as Aristotle recognized that Earth and the Moon are spheres, and understood the phases of the Moon, but because of their inability to detect stellar parallax, they rejected the idea that Earth moves. Eratosthenes measured the size of Earth with surprising precision.
Most ancient astronomers thought that all celestial objects revolved around?
Most ancient astronomers thought that all celestial objects revolved around the Earth, due to the geocentric model of the universe. This belief was held until the heliocentric model was proposed by Copernicus in the 16th century.
When was Earth the planet discovered?
The earth as planet was discovered by some of the ancient astronomers. Nicolaus Copernicus and Ptolemy are credited with provision of the initial information of the earth as a planet in relation to the solar system.
Is the shadow curved on the moon during an eclipse?
Yes. This was one of the ways that the ancient Greek and Babylonian astronomers knew that the Earth was a sphere!
Why might ancient astronomers have been convinced that the sun and moon revolve around earth?
Because in the sky it looks as if the sun is moving, but actually, the earth is moving but you can't feel it.
Scientists who study the universe beyond earth are called?
They are called astronomers.
