2. When does a comet get a tail? a. When it gets farther from the sun b. When it gets closer to the sun c. When it gets farther from the Earth d. When it gets closer to the Earth
Comets leave long beautiful tails when they come close to the sun. ... But when it approaches the sun, the heat evaporates the comet's gases, causing it to emit dust and microparticles (electrons and ions). These materials form a tail whose flow is affected by the sun's radiation pressure.
Comets develop tails as they approach perihelion—the place in their orbits when they are closest to the Sun. The Sun's heat vaporizes some of the comet's material, releasing dust particles that were trapped in the ice.
