I heard that there is planet that is ten Jupiter mass orbiting Aldebaran (Alpha Tauri). Aldebaran is a red giant star in constellation Taurus which by itself is a double star with red dwalf star. The planet orbit around Aldebaran every 2 earth years. That makes the planet about the same distance between sun and Mars. The planet is only 10 times of mass of Jupiter. It require at least 40 Jupiter mass to become a star. It is too small to be a star, but it is a very big planet orbiting around Aldebaran the red giant star.
