The two times each year when the Sun is directly overhead at noon as seen from Earth’s equator.EEquinox
88%
An interstellar cloud of dust, hydrogen, helium, and other ionized gases.NNebula
88%
The gravitationally curved trajectory of an object, such as the trajectory of a planet around a star or a natural satellite around a planet.OOrbit
86%
A minor planet orbiting the Sun, consisting of metal and rock.AAsteroid
83%
A brief streak of light caused by a small piece of solid matter entering Earth’s atmosphere at tremendous speed (typically 20 to 40 miles per second).MMeteor
83%
The distance that light (moving at about 186,000 miles per second) travels in one year, or about 6 trillion miles.LLight-year
81%
A temporary dark blemish on the surface of the Sun that is a planet-size region of gas cooler than its surroundings.SSun spot
79%
A type of astronomical body orbiting a star or stellar remnant which is massive enough to be rounded by its own gravity (but not massive enough to achieve thermonuclear fusion) and has cleared its neighbouring region of all planetesimals.PPlanet
76%
A massive ball of gas that generates prodigious amounts of energy (including light) from nuclear fusion in its hot, dense core.SStar
76%
A region on the celestial sphere surrounding a specific and identifiable grouping of stars.CConstellation
74%
A supermassive black hole gorging on gas at the center of a distant galaxy.QQuasar
74%
A highly magnetized rotating neutron star or white dwarf that emits a beam of electromagnetic radiation.PPulsar
69%
The two times each year when the Sun is farthest north or south in the sky.SSolstice
69%
A glow in the night sky or around one’s observing site caused by artificial light and greatly reducing the number of stars that are visible.LLight pollution
67%
A type of stellar remnant composed mostly of electron-degenerate matter, and lacking the mass needed to continue the nuclear fusion process with its constituent atoms, so the object's energy output normally comes from radiative cooling.WWhite dwarf
67%
A broad, faintly glowing band stretching across the night sky, composed of billions of stars in our galaxy too faint to be seen individually.MMilky Way
60%
The set of constellations situated along the ecliptic in the sky, through which the Sun, Moon, and planets move.ZZodiac
60%
Sunlight reflected by Earth that makes the otherwise dark part of the Moon glow faintly.EEarthshine
29%
Any pattern of stars recognizable in Earth's night sky. May be part of a constellation or may be composed of stars from more than one constellation.AAsterism
26%
A collection of stars orbiting a common center of mass.SStar cluster
