If the distance betwwen earth ans sum increases to double
Answers
All of the bodies in the solar system — planets, asteroids, comets, etc. — revolve around it at various distances.
The distance from Earth to the sun is called an astronomical unit, or AU, which is used to measure distances throughout the solar system.
The AU is the average distance from the Earth o the Sun. Earth makes a complete revolution around the sun every 365.25 days — one year.
However, Earth's orbit is not a perfect circle; it is shaped more like an oval, or an ellipse. Over the course of a year, Earth moves sometimes closer to the sun and sometimes farther away from the sun. Earth's closest approach to the sun, called perihelion, comes in early January. The farthest from the sun Earth gets is called aphelion.
This would make the orbital period P=2.828years.
