Answer 2

The earth moves around the sun.

There is differences in between round and around.

• Round is an adverb and preposition that has the same meanings as 'around'.
• Moving in a circular motion or following a perimeter,
• Surrounding or being surrounded by something,
• Being near to or in the general proximity of something — These are defined in the preposition 'around'.
• However, Around is more formal nowadays used in the English language.
