Revealing the 'paradox of the solar system' has a strange temperate planet

HD 164922 has up to three planets with characteristics of the planets in the Solar System, but their properties are disturbed in the style of that beard and his chin.

A team of scientists led by Dr. Serena Benatti from the Palermo Observatory of the City of Palermo (Italy) has discovered an unusual "Solar System" called HD 164922, also known as Gliese 9613 or LHS 3353 . Around the old 9.6 billion-year-old mother star, a little smaller than the sun, are three planets with the characteristics of Earth, Saturn and Neptune.

Normally, the planets will be marked with the letters b, c, d, etc., respectively, from the planet closest to the parent star. However, because the discovery of these three planets is somewhat opposite to other star systems - the farthest planets have been seen before, the names of the planets also became paradoxical. Not only that, despite the characteristics of the three planets of the Solar System, the properties of these three planets seem to be mixed together: Earth-like planets are dead, planets like Saturn then the weather is great.

A planet like Saturn - HD 164922b - orbits its star every 1,200 days and has a distance of its parent star of 2.2 astronomical units (AU, 1 AU equal to the distance from the Sun to Earth). It is a planet with a temperate climate , which means temperature and weather can be "as livable" as Earth.

The planet is a bit closer , called HD 164922c , similar to Neptune but a bit smaller, 12.9 times heavier than Earth, 75.8 days of a scrambling day and 0.35 AU from the parent star.

The innermost is a super-Earth that the team has found very difficult to find, that is, it is a rocky planet like Earth but much larger. This planet is 4 times heavier than Earth, named HD 164922d , a year is 12.5 days long. At a distance of 0.1 AU from the parent star, it's as hot as hell!

After the results have just been published in the scientific journal Astronomy & Astrophysics, the team said it could rely on the help of ESA's CHEOPS exoplanet survey satellites to learn more about them. The initial study was based on observations from an advanced spectroscopy device at the Roque de los Muchachos Observatory (La Palma, Canary, Spain).
