Astronomers have discovered an Earth-size exoplanet (外星行星), or world beyond our solar system, that may be filled with volcanoes. Called LP791-18d, the planet could experience volcanic explosion as often as Jupiter’s moon Io, the most volcanically active body in our solar system. LP791...
Astronomers are still searching for a hypothetical “Planet Nine” in the distant reaches of our solar system, but anexoplanet336 light years from Earth is looking more and more like the Planet Nine of its star system. Planet Nine, potentially 10 times the size of Earth and orbiting far ...
“This is our solar backyard, and that’s exciting,” Soares-Furtado concluded. The team wants to know what sort of information a star this close and with such a crowded system around it can provide. “How will it help us as we move on to look for planets among the maybe 100 other,...

Astronomers have had difficulty accounting for certain planets discovered outside oursolar system. They are called hot Jupiters because each is similar in mass to Jupiter, the largest solar-system planet, but orbits its parent star at a fraction of the distance at which Earth, let alone Jupiter...
1. Exo: The term "exo" is often associated with the Outer Space or something related to the external. For example, "exoplanet" refers to a planet outside our solar system, while "extrovert" describes a person who is social and enjoys being around others.2. Exothermic: An ...
