Which of the following best describes meteors?

• Solids with irregular shapes, some of which are larger than Pluto, that mostly orbit the Sun between the orbits of Mars and Venus

• Solids that range in size from dust to small rocks that are scattered throughout the solar system, often due to the breakup of comets, that burn in a brief bright display when they enter Earth’s atmosphere

• Solids made of rock and ice with very elliptical orbits that originate beyond the orbit of Neptune and release gas and dust in a bright display that can last weeks when they pass close to the Sun

• Solids that orbit many planets in our solar system, many of which are asteroids or comets that have been caught by the gravitational pull of the more massive planet they orbit
