The most star similar to our sun is Tau Ceti. Out smart your ateacher lol. but i would say ]Capella
Explanation:
Earth's rotation causes day time and night time. When the earth is tilted towards the sun, the area tilted towards the sun receives more radiation, and is probably in summer/spring. When the earth is tiled away from the sun, the area tilted away receives less sunlight, so it is probably in fall/winter.
