Over 4,000 exoplanets, or planets orbiting a sun other than our own, have been discovered in the universe since 1992 when the first exoplanet was confirmed. These planets have given answers and provided new questions about how the universe was formed and what sets our solar system apart.

In Envisioning Exoplanets, learn how exoplanets like 51 Pegasi b and TRAPPIST-1 h got their names and what those names mean. Discover ploonets, escaped worlds that are now orbiting stars, and Hot Jupiters, large, gaseous planets that are common in many solar systems. Examine scientifically informed depictions of exoplanets and stars millions of light years away from the Earth. And find out if any of these exoplanets are similar enough to our own to be considered Earth 2.0—a potentially habitable planet where humanity can thrive.
