Discover a mysterious hot planet, dense metal like Mercury

A mysterious planet with hot temperatures, rich in metal, about the same size as the Earth and the density of matter similar to Mercury found is 340 light years away.

The mysterious planet was discovered by a group of global astronomers including the University of Warwick.

The planet is named K2-229b , 20% larger than Earth but has 2.5 times more mass and reaches a day temperature of more than 2000 ° C (2330 Kelvin).

It was found to be very close to its host star (0.012 AU, about one percent of the distance between the Earth and the Sun), essentially a small average K star that operates in the Virgo Constellation region .

K2-229b has an orbital cycle every fourteen hours around the host star.

Researchers at the Aix-Marseille University in France, Dr. David Armstrong and colleagues at Warwick University's Astronomical Group discovered the planet independently, along with researchers at the University studying Porto.

Using the K2 telescope, scientists used the Doppler gravitational spectroscopy technique to explore and characterize this distant planet.

They calculated the size, position, and mass of K2-229b by measuring the radial velocity of the star, finding the oscillation of the bright star in orbit, measuring the gravitational pull from the planet, changing it to belongs to the planet size.

Dr. David Armstrong commented: "Mercury is more prominent than the other terrestrial planets of the Solar System, which contain a lot of iron but did not expect the new planet to have similar characteristics."

The dense metal nature of K2-229b has many potential origins and a hypothesis that its atmosphere may have been eroded by wind and ultraviolet rays as the planet moved near the host star. its.
