HD 37124 is a yellow dwarf star approximately 108 light-years away in the constellation of Taurus (the Bull). As of 2005, three extrasolar planets have been confirmed to orbit the star. This system is currently one of the only that contains multiple planet that are not hot Jupiters and are either near or within the habitable zone. The name of this star comes from its identifier in the Henry Draper Catalog.

Planetary system

As of 2005, three extrasolar planets have been confirmed to orbit the star. This system is currently one of the only that contains multiple planet that are not hot Jupiters and are either near or within the habitable zone. Announced in 1999, the first planet (HD 37124 b) was discovered orbiting its parent star around the inner edge of its star's habitable zone, causing the planet to have a somewhat similar insolation to that of Venus. The second planet (HD 37124 c) was discovered in 2002. This planet also orbits within its star's habitable zone, but with an insolation similar to that of Mars. The third and currently final planet discovered (HD 37124 d) was announced in 2005. Though not orbiting exactly in the habitable zone, this planet is thought to have an insolation similar to that of Jupiter. Because all planets are classified as Jovial planets, the two inner planets would be very alien in appearance, while the third planet is considered a Jupiter twin.PlanetboxOrbit
