Answer: Jupiter
Notes: Astronomers have recently found a near-identical twin of Jupiter which is located at a similar distance from its star as Jupiter is from our Sun. Named K2-2016-BLG-0005Lb, the exo-planet located 17,000 light-years from Earth, has been detected by a team of astrophysicists using data obtained by NASA's Kepler space telescope. Scientists used Albert Einstein's Theory of Relativity and a method known as gravitational micro-lensing to spot this object.
