FW Tauri has alternative name(s) :- FW Tau.

More details on star alternative names can be found at Star Names .

Location of FW Tauri

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 star is compared to the celestial equator and is expressed in degrees. For FW Tauri, the location is 04h 29m 30.00 and 26° 16` 53.00 .

Physical Properties (Colour, Age) of FW Tauri

FW Tauri has a spectral type of M4. This means the star is a red star.

The star is believed to be about 0.00 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.

FW Tauri Apparent and Absolute Magnitudes

FW Tauri has an apparent magnitude of 15.50 which is how bright we see the star from Earth. Apparent Magnitude is also known as Visual Magnitude. Using the supplied Parallax value, you would get an absolute magnitude of 9.69 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.

Distance to FW Tauri

The Parallax of the star is given as 6.90 which gives a calculated distance to FW Tauri of 472.93 light years from the Earth or 145.00 parsecs. It would take a spaceship travelling at the speed of light, 472.93 years to get there. We don't have the technology or spaceship that can carry people over that distance yet.

The star is roughly 29,908,188.50 Astronomical Units from the Earth/Sun give or take a few. An Astronomical Unit is the distance between Earth and the Sun. The number of A.U. is the number of times that the star is from the Earth compared to the Sun.
