Exoplanets And Planets: The Truth Is Out ThereOn February 22, 2017, news of the discovery of seven new exoplanets was announced by NASA. Let's examine the difference between planets and exoplanets.
An object in orbit around a star. A planet does not give off its own light; rather, it shines by reflecting sunlight. Planets close to the sun are rocky. Those farther out consist mostly of gases and liquids.
notes for planet
There are nine major planets, including the Earth, in orbit around our sun, along with many asteroids. (See solar system.)
notes for planet
Scientists have discovered evidence for the existence of many planets that circle other stars.
In the traditional model of solar systems, a celestial body larger than an asteroid or comet, illuminated by light from a star, such as the Sun, around which it revolves.
A celestial body that orbits the Sun, has sufficient mass to assume nearly a round shape, clears out dust and debris from the neighborhood around its orbit, and is not a satellite of another planet. The eight planets are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune. Pluto was considered to be a planet until its reclassification in 2006 as a dwarf planet. A planetlike body with more than about ten times the mass of Jupiter would be considered a brown dwarf rather than a planet. See also extrasolar planetinner planetouter planet.
