What are planets that circle stars other than the Sun, potentially located in habitable zones?

• A. Comets
• B. Exoplanets
• C. Nebulae
• D. Asteroids

Answer: (B)

Planets that circle stars other than the Sun are known as exoplanets. The prefix exo- means "outside," so these worlds orbit stars beyond our Solar System. Some exoplanets may lie in their star’s habitable zone—the region where, with the right atmosphere and conditions, liquid water could exist on the planet’s surface. This makes them the best fit for the description. Comets are icy bodies that travel through a solar system; nebulae are vast clouds of gas and dust; asteroids are rocky remnants orbiting stars. None of these are planets, and they don’t fit the description of planets orbiting stars outside our Sun, hence exoplanets is the accurate term.
