Massive Exoplanet Evolved In Extreme 4-Star System

astroengine writes "For only the second time, an exoplanet living with an expansive family of four stars has been revealed. The exoplanet, which is a huge gaseous world 10 times the mass of Jupiter, was previously known to occupy a 3-star system, but a fourth star (a red dwarf) has now been found, revealing quadruple star systems possessing planets are more common than we thought. "About four percent of solar-type stars are in quadruple systems, which is up from previous estimates because observational techniques are steadily improving," said co-author Andrei Tokovinin of the Cerro Tololo Inter-American Observatory in Chile. The whole 4-star family is collectively known as 30 Ari, located some 136 light-years from Earth — in our interstellar backyard. The exoplanet orbits the primary star of the system once every 335 days. The primary star has a new-found binary partner (which the exoplanet does not orbit) and this pair are locked in an orbital dance with a secondary binary, separated by a distance of 1,670 astronomical unit (AU), where 1 AU is the average distance between the Earth and sun.

    Where I come from, a solar system is defined as the union of one sun and a few planets.

    We don't go in for that kinky multi-stellar shit.

    I don't care if it's 90,000 hectares. That lake was not my doing.
