A comet tail composed of small dust particles released from the nucleus that follows the comet's orbital path, appearing curved due to radiation pressure and orbital mechanics. Dust tails typically appear yellowish-white from reflected sunlight.
From Old English 'dust' meaning fine particles and 'tægl' meaning tail. The term became standard in the 19th century as astronomers distinguished between different types of comet tails through improved telescopic observations.
Dust tails create meteor showers when Earth passes through them! The particles that make up these beautiful curved tails eventually spread along the comet's orbit, and when we encounter them, they burn up as shooting stars in our atmosphere.
