You're fishing for "comet", but the setup of your riddle is defective.
-- A comet need not necessarily be in orbit around the sun.
Its appearance may be a once-in-eternity event.
-- A comet only has a 'tail' during the small portion of its orbit
when it's relatively near the sun.
-- The whole notion of a "tail" is misleading. That particular whatchamacallit
always points away from the sun, so when the comet has rounded the sun
and is headed out again, the so-called 'tail' goes in front of it.
They are called comets.
Comets are icy/rocky objects that orbit our Sun.
Tails, not trials. They're called comets, and their "tails" form when the comet gets near the sun, vaporizing away some of the ice.
Ice Kitties in Space! No? How about comets?
They could be the kuiper belt. Pluto orbits with them.
Comets sound like the answer to your question.
Both comets and Kuiper Belt Objects would fit that description.
Comets are small bodies of rock and ice which are in a highly eccentric orbit around the sun. They spend most of their time slowly orbiting the sun, far out beyond the outer planets. Their orbit eventually comes close to the sun, where the surface is heated and gives the comet its tails. They are thought to be objects from the Kuiper belt, a group of icy rocks far out beyond the orbit of Neptune. Gravitational effects of the planets and other objects may knock these off their regular orbits into the highly eccentric comet orbit.
icy objects travel around the sun
No; some objects orbit OTHER objects, not themselves.No; some objects orbit OTHER objects, not themselves.No; some objects orbit OTHER objects, not themselves.No; some objects orbit OTHER objects, not themselves.
The comets get their tails by going nearer the sun and the icy hard rock starts to melt.
Objects and planets orbit the sun because of the sun's gravitaional pull.
Small icy bodies are located in the solar system where they orbit the sun.
Moons. They orbit their planets, not the Sun.
Objects that move around the sun orbit the sun. (Objects such as planets actually orbit the sun in an oval.)
This is a qualifying phrase that is asking you to decide whether each condition that follows it does or does not fit for objects that orbit the Sun.
the tails will be longest when it goes past the sun because of the light
