- Spica – it’s actually a spectroscopic binary (double star) in the constellation Virgo, with two massive blue‑white stars orbiting each other about every 4 days.
o - Binoculars
Even with good binoculars, Spica still appears as one point of light.
o - Telescope
Only very large professional telescopes (or advanced spectroscopic equipment) can detect the two stars ~ they’re separated by less than 0.1 arcseconds — far below the resolution of amateur telescopes.
