is the number of times that the star is from the Earth compared to the Sun. In a non-canonical chapter in Re:Zero -Starting Life in Another World-, Subaru had a daughter with Rem named Spica. The spectrum shows a radial velocity variation with the same period, indicating that the surface of the star is regularly pulsating outward and then contracting.

Alongside United Airlines, it is one of only two airlines worldwide operating the Boeing 767-400ER.

Luminosity is the amount of energy that a star pumps out and its relative to the amount that our star, the Sun gives out. The number of A.U. Which time the airline operated the world's largest fleet of 727-200, 129 aircraft. The WGSN's first bulletin of July 2016[13] included a table of the first two batches of names approved by the WGSN; which included Spica for this star. [3] It is a spectroscopic binary star and rotating ellipsoidal variable; a system whose two stars are so close together they are egg-shaped rather than spherical, and can only be separated by their spectra. Located about eight degrees northwest of Delta Virginis almost directly between a pair of 6th magnitude stars (RA 12 29 46 Dec +07 59 59), the giant elliptical galaxy M49 … Its brightness changes are tied to its absolute brightness. The MK spectral classification of Spica is typically considered to be an early B-type main sequence star. In 2016, the International Astronomical Union organized a Working Group on Star Names (WGSN)[12] to catalog and standardize proper names for stars. Based on the star's spectral type of A0/1 IV , Heze's colour and type is blue - white subgiant star. It should not be taken as though the star is moving closer or further away from us. 1", "AEEA 天文教育資訊網, Activities of Exhibition and Education in Astronomy", Bulletin of the American Astronomical Society, Journal of the Royal Astronomical Society of Canada, "Follow the arc to Arcturus, and drive a spike to Spica |", "Observation of 23 Supernovae That Exploded <300 pc from Earth during the past 300 kyr", "Photospheric Heating in Colliding-Wind Binaries",, Articles with unsourced statements from February 2019, Articles containing Chinese-language text, Articles containing explicitly cited English-language text, Creative Commons Attribution-ShareAlike License, This page was last edited on 9 September 2020, at 00:25.

Using the original Hipparcos data that was released in 1997, the parallax to the star was given as 44.55000 which gave the calculated distance to Heze as 73.21 light years away from Earth or 22.45 parsecs. They stay close together enough that they cannot be resolved as two stars through a telescope. Messier 49 can be found 4.1 degrees to the west-southwest of the star Vindemiatrix, Epsilon Virginis, a yellow giant with a visual magnitude of 2.8.

[21][22], Spica is 2.06 degrees from the ecliptic and can be occulted by the Moon and sometimes by planets. This lack of synchronization and the high ellipticity of their orbit may indicate that this is a young star system.

Johann Bayer cited the name Arista. Coordinates: 13h 25m 11.5793s, −11° 09′ 40.759″, This article is about the star. It is purely that the distance was recalculated.

The evolutionary stage has been calculated to be near or slightly past the end of the main sequence phase. The star's Galacto-Centric Distance is 7,391.00 Parsecs or 24,106.73 Light Years. Other traditional names are Azimech /ˈæzɪmɛk/, from Arabic السماك الأعزل al-simāk al-ʼaʽzal 'the unarmed simāk' (of unknown meaning, cf. [19] A temple to Menat (an early Hathor) at Thebes was oriented with reference to Spica when it was built in 3200 BC, and, over time, precession slowly but noticeably changed Spica's location relative to the temple.

[27], The secondary member of this system is one of the few stars whose spectrum is affected by the Struve–Sahade effect. The Sun's radius is 695,800km, therefore the star's radius is an estimated 1,463, Information regarding Metallicity and/or Mass is from the E.U. The items in red are values that I've calculated so they could well be wrong. If the R.A. is positive then its eastwards.
