EPIC 228735255

EPIC 228735255 Facts

Location of EPIC 228735255

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 EPIC 228735255, the location is 12h 32m 32.96 and -09° 36` 27.50 .

Physical Properties (Colour, Metallicity, Age, Radius) of EPIC 228735255

EPIC 228735255 Colour and Temperature

EPIC 228735255 has a spectral type of G5. This means the star is a yellow star.

EPIC 228735255 Radius

EPIC 228735255 has been calculated as 0.99 times bigger than the Sun. The Sun's radius is 695,800km, therefore the star's radius is an estimated 686,754.60.km. If you need the diameter of the star, you just need to multiple the radius by 2.

The star's metallicity is 0.045000, 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 4.22 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.

EPIC 228735255 Apparent and Absolute Magnitudes

EPIC 228735255 has an apparent magnitude of 12.60 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 4.94 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 EPIC 228735255

The Parallax of the star is given as 2.94 which gives a calculated distance to EPIC 228735255 of 1109.74 light years from the Earth or 340.24 parsecs. It is about 744,210,097,866 miles from Earth.

The star is roughly 70,179,048.66 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.

Travel Time to EPIC 228735255

The time it will take to travel to this star is dependent on how fast you are going. U.G. has done some calculations as to how long it will take going at differing speeds. A note about the calculations, when I'm talking about years, I'm talking non-leap years only (365 days).

The New Horizons space probe is the fastest probe that we've sent into space at the time of writing. Its primary mission was to visit Pluto which at the time of launch (2006), Pluto was still a planet.
