While it’s true Venus spins clockwise, in the opposite direction to Earth, the same is true for Uranus – and dwarf planet Pluto. But if yourewatching from over the south pole, then youd swear the earth rotates clockwise.Youd be correct in both cases. Pluto was once considered our solar system's ninth planet. An observer would see a similar eastward motion over the South Pole, but from this perspective the motion would be clockwise. If youre hanging over the north pole watching it, then youd say it does. And unlike any other planet, Uranus rotates on its side,” says Nasa.ĭwarf planet Pluto also rotates clockwise – or “retrograde”, from east to west – like Venus and Uranus. “Like Venus, Uranus rotates in the opposite direction as most other planets. Uranus is the seventh planet orbiting the sun. There are two planets that “spin on their axes from east to west”, according to the New York Times – Venus and Uranus. Uranus and dwarf planet Pluto also rotate clockwise This unusual axis rotation “is due to being upside down”, according to the Royal Museums Greenwich in the UK.īut Venus isn’t the only planet that rotates differently to its solar system neighbours. Īlthough Venus orbits the sun in an anticlockwise fashion like all the other planets in our solar system, it rotates clockwise about its axis. Not only is its day longer than its year and it doesn’t experience seasons, but “Venus spins backward”, says Nasa. Venus is often called the “twin” of Earth, but it has significant differences. So is Venus the only planet rotating the other way? We investigated.Įight planets orbit Earth’s star, the sun: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune.īeyond Neptune, there are smaller worlds called dwarf planets which include what the US’s National Aeronautics and Space Administration, or Nasa, calls the “longtime favorite Pluto”. Venus is Earth’s nearest planetary neighbour and the second planet from the sun.Įarth rotates on its axis in an counterclockwise direction, the opposite direction of the hands of a clock.

A more appropriate question would be why do the planets orbit in the. As the bob swings back and forth, it slowly moves in a clockwise direction as the Earth rotates under it. When viewed from the south side, the earth orbits the sun clockwise and rotates clockwise. A heavy, swinging lead bob is suspended at the end of a line. While they vary in size, pendulums work best with long lines, typically between 40 and 100 feet. While the theory became accepted by the mid-1800s through observation of astronomical movements, it was Foucault’s pendulum that demonstrated, visibly and spectacularly, the rotation of the Earth.įoucault first conducted his pendulum experiment in the Paris Observatory, then the Panthéon, where it remains an impressive centerpiece today. Following his work, others tried to prove the rotation of the Earth through various experiments. Arguably the earliest scientific observations, these records make astronomy the oldest known science.Īlthough humans have observed the stars for thousands of years - some early theories proposed that the Earth moved - the geocentric theory remained dominant in Europe until the work of Nicolaus Copernicus in the 1500s, proving the Earth does actually revolve around the sun. A bronze disk found in Northern Europe shows the sun, a crescent moon, and the Pleiades star cluster, and written records from the Babylonians record the position of celestial bodies. The first human depictions of the cosmos date back to 1,600 BCE. In the 10th century CE, Muslim astronomers started building astrolabes and other instruments to measure the movement of the Earth relative to the stars. At the centre of the earth is a huge ball of liquid iron. The Earth rotates once in about 24 hours with respect to the sun and once every 23 hours, 56 minutes and 4 seconds with respect to the stars (see below). What force makes the earth rotate on its own axis Could its rotation ever slow down. As far back as 470 BCE, ancient Greeks speculated the Earth itself moves, rather than having the rest of the sky revolving around us. As viewed from North Star or polestar Polaris, the Earth turns counter-clockwise. The rotation of the Earth and its relationship to our daylight cycles has fascinated philosophers and scientists for thousands of years.
