Tau Virginis
What is Tau Virginis
Tau Virginis is a white A-type star on the eastern flank of the Virgin, a region of the sky known to host a swarm of distant galaxies beyond its apparent glow. It is surrounded by a dust disc detected in the infrared, perhaps the remnant of a primitive planetary system still under construction. Its light, after travelling 225 years, reached Earth as the nineteenth century was about to begin.
Where it is and when to see it
Tau Virginis lies in the northern celestial hemisphere. It is visible to the naked eye under a dark sky. Its best month of the year is April, when it culminates around midnight.
