Alien Planet's Spin Cycle Determined 63 Light Years Away

Scientists announced this week that they have measured the spin cycle of a planet outside our solar system for the first time ever.

The large gas planet measured is roughly 63 light years away from Earth, according to Reuters.

They confirmed that the planet spins faster than any planet in our solar system, with a rotational velocity at its equator of about 56,000 mph.

In comparison, Jupiter, a large gas planet that has the quickest spin in our solar system, spins at approximately 29,000 mph, while Earth spins at about 1,000 miles per hour.

A day on Beta Pictoris b lasts just eight hours, which is two hours less than a day on Jupiter, and 16 hours less than a day on Earth.

At least 1,800 planets have been spotted outside our solar system, but not much is known about these worlds besides basic information like what they're made of and how they travel around their stars, according to Reuters.

Beta Pictoris b is one of the more understood distant planets however, as it is only one of 12 that have been directly observed, rather than found by using indirect detection devices.

"Only if we know more about other planets - like temperatures, atmosphere and rotation - can we tell how unique our home in the universe really is," said one of the researchers, Bernhard Brandl, an astronomy professor at the University of Leiden in the Netherlands, according to Reuters.

The planet is approximately 3,000 times larger than Earth and seven times bigger than Jupiter, which is commonly known as our solar system's largest planet.

It is only about 20 million years old, and is supposedly "still hot" from its formation, according to Reuters.

Beta Pictoris, the planet's host star, is about twice as large and 10 times as bright as our Sun.

"Yes, the relation between mass and spin velocity was already known in our solar system," said University of Leiden astronomy professor Ignas Snellen, another of the researchers involved in the discovery, according to Reuters. "We now extend it to a more massive planet to see that the relation still holds. We need to observe more planets to confirm this is really a universal law."

Beta Pictoris b was discovered about six years ago, and orbits eight times farther from its host star than Earth orbits the Sun, according to Reuters.

Research was published in the journal Nature this week.
