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 The radiation pressure again can be seen as the transfer of each photon's momentum to the opaque surface, plus the momentum due to a (possible) recoil photon for a (partially) reflecting surface.
Can Comets have no tails?
A strange, rocky comet with no tail has been spotted zipping into our inner Solar System, and it's so unique, it's got scientists ready to rewrite the definition of what these ubiquitous cosmic bodies should look like.
Do comets and meteors have tails?
The dust and gas are pushed away from the Sun by the solar wind and radiation pressure, producing the comet's tail (which always points away from the Sun, by the way). ... A Meteor on the other hand, is a grain of dust or rock (see where this is going) that burns up as it enters the Earth's atmosphere.
