Add your touch to the coloring page for 51 Pegasi b based on our popular Exoplanet Travel Bureau poster that shows various post cards for first exoplanets discovered.

51 Pegasi b stands out among the first exoplanets discovered. It’s about half the mass of Jupiter, with a star-hugging orbit that means its “year” is only 4.2 Earth days! It is the first planet confirmed to orbit a Sun-like star, and it ushered in a new class of planets called “Hot Jupiters”: massive planets orbiting extremely close to their stars. What colors would light up the first exoplanets discovered?
