Mascara-1

Mascara-1 Facts

Location of Mascara-1

The location of the star in the night sky is determined by the Right Ascension (R.A.) and Declination (Dec.), these are equivalent to the Longitude and Latitude on the Earth. The Right Ascension is how far expressed in time (hh:mm:ss) the star is along the celestial equator. If the R.A. is positive then its eastwards. The Declination is how far north or south the object is compared to the celestial equator and is expressed in degrees. For Mascara-1, the location is 21:10:12.4 and +10:44:20 .

Physical Properties (Colour, Age, Mass, Radius) of Mascara-1

Mascara-1 Colour and Temperature

Mascara-1 has a spectral type of A8. This means the star is a blue - white star.

Mascara-1 Radius

Mascara-1 has been calculated as 2.10 times bigger than the Sun. The Sun's radius is 695,800km, therefore the star's radius is an estimated 1,461,180.00.km. If you need the diameter of the star, you just need to multiple the radius by 2. The star's solar mass is 1.72 times that of the Sun's. The Sun's Mass is 1,989,100,000,000,000,000,000 billion kg. which to calculate using this website is too large. To give idea of size, the Sun is 99.86% the mass of the solar system.

The star's metallicity is 0.000000, this value is the fractional amount of the star that is not Hydrogen (X) or Helium (Y). An older star would have a high metallicity whereas a new star would have a lower one.

The star is believed to be about 1.00 Billion years old. To put in context, the Sun is believed to be about five billion years old and the Universe is about 13.8 billion years old.

Mascara-1 Apparent and Absolute Magnitudes

Mascara-1 has an apparent magnitude of 8.30 which is how bright we see the star from Earth. Apparent Magnitude is also known as Visual Magnitude. Magnitude, whether it be apparent/visual or absolute magnitude is measured by a number, the smaller the number, the brighter the Star is. Our own Sun is the brightest star and therefore has the lowest of all magnitudes, -26.74. A faint star will have a high number.
