How far is the Earth to the sun?
The distance ranges between about 91 million miles and 94.5 million miles. Interestingly, the seasons do not depend on the distance of earth to sun, instead on the tilt of the earth.

How big is the Earth?
The Earth is nearly 13,000 kilometres (km) wide. It's the largest terrestrial planet in the Solar System.
The Earth weighs 5,973,700,000,000,000,000,000,000 kilograms (kg). That's nearly 6 trillion trillion kg. That's a lot. But it's little compared with Jupiter ({insert weight}) and tiny compared with the Sun ({insert weight}) or other stars!
