brightness

But some road users say their brightness can be a nuisance.

Vanessa Alarcon, the astrological observer at the Griffith Observatory, said it can be challenging for the human eye to notice these differences in size and brightness, but that shouldn’t stop people from trying.

While the brightness will start to decrease, it will still be possible to see the bright comet on Tuesday night - weather permitting.

RAS said the object has been called the "comet of the century" because of its impressive brightness and visibility.

The exact intensity of Tsuchinshan-ATLAS’s brightness is tough to predict; the comet is still light-years away from Earth, after all.
