The Earth spins on an axis.

Answer 1

The two important astronomical discoveries Guptas made was that first the earth is round and it spins on an axis, this is true because we known the earth is round shape like a soccer ball and it does NOT revolve around the sun, the sun revolves around the EARTH, and the earth doesn't revolve around the moon but rather it spins on an axis which is the reason our seasons keep changing.

Answer 2

The Gupta astronomers made many advances in astronomy, using their mathematical knowledge.

It was during this empire that the philosophers of India proposed the idea that the earth was not flat, but was round and rotating on an axis which allowed to see the lunar eclipses.

The answer is: The earth is round, and the Earth spins on an axis.
