The Earth rotates on its own axis and goes around the Sun in a definite orbit. The orbit is the path of the Earth around the Sun.
The difference between Earth's farthest point (about 152 million km) from the Sun and its closest point (147 million km) is very small. Earth travels around the sun at a speed of 1,07,200 kilometres per hour! At this speed, it takes 365¼ days to complete one revolution. We call this a ‘year.’
Travel of the Earth around the Sun causes the seasons like winter and summer.
