Facts about Spica
- 08
Approximately 7 million years ago, Spica will eventually collide with or be ejected from its binary system due to gravitational interactions and stellar evolution.
- 07
In ancient astronomy, Spica served as one of the four royal stars of Persia, recognized alongside Aldebaran, Antares, and Fomalhaut for navigational and astrological significance.
- 06
Spica's rapid rotation causes it to spin completely on its axis every 1.6 days, flattening its equatorial region into an oblate spheroid shape.
- 05
Around 7,000 times more luminous than our Sun, Spica's extreme brightness allows astronomers to study its stellar characteristics through detailed spectroscopic analysis despite its vast distance.
- 04
Spica's mass exceeds our Sun by approximately 7 times, making it a massive blue giant star destined to exhaust its hydrogen fuel in just a few billion years.
- 03
Spica's surface temperature reaches approximately 7,400 Kelvin, making this Alpha Virginis star significantly hotter than our Sun's 5,778 Kelvin surface.
- 02
At approximately 262 light-years from Earth, Spica ranks as the fifteenth brightest star visible in our night sky despite its tremendous distance.
- 01
The brightest star in Virgo, Spica, orbits with a companion star every 4.014 days in an eclipsing binary system.
