Question

is it correct to say that the Earth moves around the sun with constant velocity?​

Answer 1

Explanation:

No, it does not. For it to hold a constant speed, it would have to be a perfectly circular orbit. The earths orbit is not circular, with perihelion at 147,098,290km and aphelion at 152,098,232 km. According to wikipedia, the average speed the earth orbits the sun at is 107,200 km/h. The change in speed is very gradual, so you don't need to worry about the planet suddenly accelerating :
