It's called a comet. They're usually cimposed of rock and ice. As the object gets close to the sun, the heat causes the ice to evaporate, and the rock to melt. This is seen as the comet's 'tail'.
A comet
A comet (a dirty snowball) is a mix of ice, dirt and rock. It orbits is a wide oval coming closest to the sun at it's perigee It's apogee is it's farthest point. As a comet comes close to the sun, the ice sublimates (turns directly from ice into steam). When a comet comes closest to the sun the tail is largest.
It is probably because it is dominant of its sister. If this gets much worse it might be an idea to separate them. My friends gerbil bit off its brothers tail... so... this is something you need to watch.
Frozen lumps of gas and rock are known as comets. Comets heat up when passing close to the Sun, leaving a visible tail sometimes able to be seen from Earth.
Comets are made mostly of water ice and rock, and as they get close to the sun, the heat vapourises the ice and the solar wind blows the vapour and debris away, meaning that the tail always points away from the sun.
