Astronomers know that just as large objects from space have cause catastrphes on Earth in the past they are likely to do so again in the future. By finding such objects and calculating their paths they learn which ones have paths that intersect Earth's orbit. By calculating when and where that will happen they discover which ones are a threat to Earth. With such advance warning they can send a spacecraft to the object to change its path so it is no longer a threat. For example, astronomers know that a large object will pass close to Earth on Friday the 13th of April 2029. It will miss Earth, but it will be so close that it will be closer than our communication satelites.

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.

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.
They are called astronomers.
Parallax is the method that astronomers use to measure the distance from the sun to the earth.
Arab astronomers determined that the Earth was round in shape through a combination of observations and mathematical calculations. They also accurately calculated the Earth's circumference to an impressive degree of accuracy for their time.
