Second alignment plane of solar system discovered

A study of comet motions indicates that the solar system has a second alignment plane. Analytical investigation of the orbits of long-period comets shows that the aphelia of the comets, the point where they are farthest from ...

Okay, new idea: 'Oumuamua is an interstellar 'dust bunny'

Explaining the concept of a dust bunny to small children can be quite amusing. No, it's not actually alive. It's moving around because of really small currents of wind that we can't even see. It's mainly formed out of dead ...

Comet

A comet is a Small Solar System Body that orbits the Sun. When close enough to the Sun, a comet exhibits a visible coma (fuzzy "atmosphere"), and sometimes a tail, both because of the effects of solar radiation upon the comet's nucleus. Comet nuclei are themselves loose collections of ice, dust and small rocky particles, ranging from a few kilometers to tens of kilometers across.
