Earth's orbit around the Sun, showing at which stages the northern hemisphere goes through it's different seasons. When tilted away from the Sun we get Winter, when tilted towards the Sun we get Summer, and the start of Spring and Autumn is when the Earth isn't tilted in either direction, so the Sun's rays spread across both hemispheres evenly.

Sputnik 1 ("Satellite-1"), was the first artificial Earth satellite. The Soviet Union launched it into an elliptical low Earth orbit on 4 October 1957. It was a 58 cm (23 in) diameter polished metal sphere, with four external radio antennae to broadcast radio pulses. It was visible all around the Earth and its radio pulses were detectable. This surprise success precipitated the American Sputnik crisis and triggered the Space Race, a part of the larger Cold War.

We worked out how many trips each of the solar system's eight planets has taken around the sun over the past 4.6 billion years.

The Earth's orbit influences much of our lives, from the length of our year to the changing of the seasons. We are travelling at a speed of approximately 30 kilometres per second or 110 million metres per hour around the Sun yet we don't feel ourselves moving! The Earth takes 365 and a quarter days to orbit the Sun, giving us our 365 day year with an extra day once every four years as a 'leap year'. The Earth is also spinning on an axis, tilted at 23°. This means that different parts of the…
