Answer:
1) The Earth orbits the sun once every 365 days and rotates about its axis once every 24 hours. Day and night are due to the Earth rotating on its axis, not it's orbiting around the sun. The term 'one days' is determined by the time the Earth takes to rotate once on its axis and includes both day time and night time.
2) Nicolaus Copernicus was an astronomer who proposed a heliocentric system. The heliocentric theory is important today, because it led to the advancement and accuracy in astronomical tools, both physical and mathematical and changed the way scientist understand the design of our solar system.
3) The geocentric model says that the Earth is at the center of the cosmos or universe, and the planets, the sun and the moon, and the stars circles around it while the early heliocentric models consider the sun as the center, and the planets revolve around the sun.
