NASA 3 finds an alien planet with the sun

NASA has discovered an exoplanet with three stars, with a bizarre orbit that baffles astronomers.

The planet, known as KOI-5Ab, was discovered by NASA’s Kepler space telescope in 2009, but was “abandoned” by scientists because space telescopes had easy candidates to identify.

“The KOI-5AB was abandoned because it was complex and we had thousands of candidates,” said David Ciardi, chief scientist at NASA’s Exoplanet Science Institute, in a statement. “There were easier selections than the KOI-5Ab and we were learning something new every day from Kepler, so that the KOI-5 was mostly forgotten.”

KOI-5Ab is about 1,800 light years from Earth. A light year, which measures distance in space, is about 6 trillion miles.

However, thanks to NASA’s Transiting Exoplanet Survey Satellite (TESS) and other Earth-based telescopes, KOA-5Ab has been given new life, researchers have discovered its perplexing orbit.

Because of its size, KOA-5Ab is likely a gas giant similar to Jupiter or Saturn, but it orbits a star once every five days in its star system, the KOA-5A. It is out of alignment with at least one of the other two wires and possibly both.

“We do not know of many planets that exist in the triple-star system and this one is extra special because its orbit is oblique,” Sirdi said. “We still have many questions about how and when planets can form in a multiple-star system and how their properties compare to planets in a single-star system. By studying this system in more detail, perhaps we can get information about how the universe makes planets. “

In contrast, KOI-5A class KOI-5B each other, once every 30 years. KOI-5C orbits both once every 400 years, dropping four celestial objects into oblique orbit as a result of different planes.

It is unclear what caused the oblique orbit, although they believe the second star kicked the planet during the evolution of gravity, slanting its orbit and causing it to migrate inward, “NASA’s statement Is stated in. It is assumed that the triple-star system is about 10 percent of all star systems.

The findings were recently presented at a virtual meeting of the American Astronomical Society.

Researchers have discovered other planets with three stars in recent memory. In July 2019, the Exoplanet LTT 1445Ab was found to orbit one of three suns, all of which are described as mid-to-late red dwarfs.

In September 2020, researchers discovered that the GW Orionis star system, which is located on the edge of the Orion planetarium, has two stars orbiting each other with a third sibling, approximately 740 million miles between the two siblings. Let’s revolve. There may be dust inside the rings, or the introduction of a young exoplanet, which may explain the misuse of the system’s gravitational bridge.

A total of more than 4,000 exoplanets have been discovered by NASA, of which around 50 were considered potentially habitable until September 2018. They have the right size and the correct orbit of their star to support surface water, and at the very least, support life naturally.
