d. 750
ANSWER: 650
Scientists have found that a star system 650 light years away known to have a hot Jupiter planet is hosting 2 exoplanets. This discovery was made by astronomers from University of Michigan working with MIT colleagues. Hot Jupiters are called so because of their massive size and gaseous composition. However, these hot Jupiters in faraway solar systems orbit at distances closer than Mercury. Close to 300 hot Jupiters have been identified so far. This marks the first time any close in planets were discovered. Person who first spotted the planet companion in the WASP-47 system was citizen scientist Hans Schwengeler.
