$\huge\tt\fcolorbox{purple}{blue}{Answer:-}$

The Earth is one of several planets that orbit the sun, and the moon orbits the Earth. The Earth is essentially a sphere and the sun is a nearby star which is an unimaginably large ball of gas that radiates light and heat as products of nuclear reactions.

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 its orbiting around the sun. The term ‘one day’ is determined by the time the Earth takes to rotate once on its axis and includes both day time and night time.
