What is the surface temp of Spica?

39,860 degrees Fahrenheit
Spica is a blue-white gem of a star, and, for stars, color reveals the star’s surface temperature. Spica’s blue-white complexion shows that its surface temperature is extremely high (39,860 degrees Fahrenheit, or 22,127 degrees Celsius).

What is the temperature and luminosity of Spica?

Spica has a spectral type of B1V, a surface temperature of 22,400° Kelvin and a luminosity 12,100 times the Sun. It has a mass of 10.3 solar masses and a diameter 7.4 times the Sun.

Is Spica hotter than the sun?

Spica is a close double star The star Spica – aka Alpha Virginis – is the brightest star in the constellation Virgo the Maiden. The pair are both larger and hotter than our sun, and they’re separated by only 11 million miles (less than 18 million km). They orbit their common center of gravity in only four days.

Is Spica hot or cold?

A star such as Spica is one of the hottest things you can ever see. Spica’s surface is 40,000 degrees Fahrenheit, which beats arc welding, though not lightning, which can reach 90,000 degrees. A few rare stars visible in amateur telescopes exceed 100,000 degrees.

What star is hotter Betelgeuse or Spica?

Stars as large as Betelgeuse are very unusual. In contrast, Rigel, the bright, bluish-white star at the southwest corner of Orion, is smaller and much hotter than Betelgeuse. Spica is also a bluish star with a surface temperature of around 20,000 degrees Kelvin, over three times as hot as the sun.

Is Spica a high mass star?

This is a massive star with more than 10 times the mass of the Sun and seven times its radius. The bolometric luminosity of the primary is about 20,500 times that of the Sun, and nine times the luminosity of its companion.

What is the surface temperature of Pollux?

4,865 K
Pollux/Surface temperature

Pollux has a spectral type of K0III, a surface temperature of 4865° Kelvin and a luminosity 32 times the Sun. It has a mass of 1.86 solar masses and a diameter 8 times the Sun.

What is Rigels surface temperature?

11,000 K
Rigel/Surface temperature

What is the life cycle of Spica?

Spica A, for example, will live a “normal” lifetime of less than 30 million years, compared to about 10 billion years for the Sun. When it can no longer produce nuclear reactions in its core, the core will collapse.

Why is Arcturus red?

When Arcturus’ supply of hydrogen was fully depleted, it transitioned into its red giant status and astronomers believe it is now fusing helium into carbon in its core instead (which helps explain why it shines brightly and produces so much heat).

Is Pollux hotter than the sun?

Draw an imaginary line from Rigel through Betelgeuse to star-hop to Castor and Pollux. Pollux science. Pollux is classified as a “K0 IIIb” star. The K0 means that it is somewhat cooler than then sun, with a surface color that is a light yellowish orange.

How hot does it get on Mercury?

“From the night, Mercury’s surface temperature changes 1,130 °F (630 °C), more than any other planet or moon in the solar system. Just before sunrise on a typical day on Mercury the temperature is -300 °F (-180 °C).

What is the surface temperature of Spica?

Spica has a spectral type of B1V, a surface temperature of 22,400° Kelvin and a luminosity 12,100 times the Sun.

What does the Sun look like from the surface of mercury?

From the surface of Mercury, the Sun would appear more than three times as large as it does when viewed from Earth, and the sunlight would be as much as seven times brighter. Mercury’s surface temperatures are both extremely hot and cold. Because the planet is so close to the Sun, day temperatures can reach highs of 800°F (430°C).

What happens to the surface of mercury during the day?

During the day the temperature is so high that it could melt some metals and during the night the temperature drops well bellow freezing. Due to the extremely high temperatures and solar radiation on the surface of mercury during the day, the surface of the planet is dry and barren.
