Originating in the Oort cloud or the Kuiper belt
Their impact can be potentially felt; disturbing nations
Attracted to the Sun by gravitational perturbations
Influenced by stars and the galactic tide
Drawing closer, its temperature intensifies
Solar radiation pressure lessened the solid state
Enabling the comet to sublimate
Volatile materials of its nucleus
Immediately surrounding it with nebulous
Consisting of gas which was previously trapped
The centre streams out, bringing along dust
Resulting in the formation of a coma
Solar wind streams from the corona
Particles are released from beneath
By high temperatures providing them with energy
To escape its gravity, going on to form a tail
Composed of gas and the other of dust on a vast scale;
Both distinct, pointing in different directions
Tails of dust can form an antitail, an unusual projection
Caused by the velocity of the orbit
Instead of facing away from the Sun, it faces towards it
Dust tails reflect sunlight directly
Contrasted to an orbital trajectory
Gas tails are strongly affected to the magnetic field of plasma;
A substance far hotter than magma
Causing its tail to point along the solar wind streamlines
Wherever they're travelling, comets leave a trail of dust behind
Their revolution is a highly eccentric ellipse
Its course around another body is never spherical, it deviates from it
This is one of the main characteristics of a comet
