Asteroid tracker: Asteroid big enough to BLOCK OUT STARS will pass TOMORROW

Such occultations are typically the perfect opportunity for astronomers to get a glimpse of an asteroid’s shape and size.

Sirius A is the brightest star of the night sky and is almost twice as bright as the next brightest star, Canopus.

The star is accompanied by a faint white dwarf, dubbed Sirius B, and is roughly twice the size of our Sun.

Astronomers believe the star is slowly hurtling toward our system, meaning it will gradually increase in brightness.

Tomorrow, however, the star will appear to blink in and out of existence as Asteroid Jurgenstock completes its lap around the Sun.
