The tail is not of light itself, but consists of icy particles (mostly gas) reflecting light from the sun. Such objects are known as comets.
Comets that originate from the Kuiper Belt, a ring of dirty ice balls in orbit out beyond Neptune, are short period comets. They orbit the sun once a century or so, until all the ice and gas burn off and they probably become asteroids. Comets from much further out (the Oort Cloud) generally do not orbit in the plane of the solar system, and are usually long period comets. These orbit only once every few thousand years, sometimes only once per hundred thousand years or more.
Comets do as the sun melts some of the ice they contain.
Ice Kitties in Space! No? How about comets?
you mean comets?
That is a comet.
A Comet, and the tail is it's coma.
Comets.

No. The truth is the exact opposite. Every object in a closed orbit around the sun ...every planet, asteroid, periodic comet, etc. ... has an elliptical orbit.
Comets do indeed have orbits. Sometimes the orbits take thousands of years. For the most part, they stay in these orbits unless affected by the gravity of another body.
Yes, just like all celestial body with a closed orbit. If you want to be specific, the orbit of the moon is spiral, since it is moving away from us at a pace of 3 cm per year.
The orbit is elliptical, and in simple cases, the centre of the two bodies' mass is at one of the foci of the ellipse.
Virtually NOTHING in space is in a circular orbit; every body out there is in an elliptical orbit. Some are CLOSE to circular, but I don't believe than any are quite exact. Comets especially are in VERY elliptical orbits. If their orbits were even nearly circular, their ices and volatile gasses would have been evaporated long ago.

No, everything in orbit around the sun has an elliptical orbit, some are just closer to being in a circular orbit than others.
A satellite in an elliptical orbit gains speed as it draws closer to the central body and loses speed as it moves farther away from the central body.
No. The truth is the exact opposite. Every object in a closed orbit around the sun ...every planet, asteroid, periodic comet, etc. ... has an elliptical orbit.
An orbit is the circular or elliptical motion of one smaller body around another larger body due to gravitational attraction.
A planet is a spherical body that has an elliptical orbit around a certain mass, while a meteorite is a small chunk of rock that is hurtling through space with no orbit towards any mass.
You didn't specify which astronomical body you're referring to, but nearly all orbits are elliptical.
Comets do indeed have orbits. Sometimes the orbits take thousands of years. For the most part, they stay in these orbits unless affected by the gravity of another body.
An apoapsis is the point of a body's elliptical orbit around the system's centre of mass where the distance between the body and the centre of mass is at its maximum.
Yes, just like all celestial body with a closed orbit. If you want to be specific, the orbit of the moon is spiral, since it is moving away from us at a pace of 3 cm per year.
An apocentre is another name for an apoapsis, the point of a body's elliptical orbit around its system's centre of mass where the distance between the body and the centre of mass is at its maximum.
The primary body, earth, is at the foci point closest to the pedigree. At the pedigree the radius is shorter than it is at the apogee.
