Stellar eclipse gives glimpse of exoplanet: New data reveals a ‘super-Earth’ next door, astronomically speaking

The far-out planet, named 55 Cancri e, is twice as big as Earth and nearly nine times more massive. It is most likely composed of rocky material, similar to Earth, supplemented with light elements such as water and hydrogen gas. Scientists estimate the planet’s surface is much hotter than ours: close to 2,700 degrees Celsius.
