Malaysia tourism for In particular, it had a series of outbursts separated by about to weeks. Moreover, comets, particularly medium or large dusty ones, are subject to brightness boosts when they come close to the imaginary line that cuts through Earth and the Sun, due to the forward-scattering or backscattering of the Sun’s light. To put it simply, as a comet moves closer to the zone between the Sun and Earth, the Sun’s light hits the small dust particles of the coma and tail and is scattered forward. The result is that the coma and the dust tail are subject to an increasingly large spike in brightness. It is just like when a spider’s web is between you and the Sun the web suddenly becomes stunningly visible as the sunlight strikes it and is scattered forward in your direction. See fig.
