A3 is the brightest comet since Hale-Bopp in 1997. So it's been 27 years since we have had such an amazing opportunity to view the true travelers of the solar system.
A comet is an icy, small Solar System body that warms and begins to release gases when passing close to the Sun, a process called outgassing. This produces an extended, gravitationally unbound atmosphere or coma surrounding the nucleus, and sometimes a tail of gas and dust gas blown out from the coma. These phenomena are due to the effects of ...
