Wolf 357

Wolf 357 Facts

  • Wolf 357 is a star that can be located in the constellation of Leo Minor. The description is based on the spectral class.
  • Wolf 357 is not part of the constellation outline but is within the borders of the constellation.
  • Based on the spectral type (K2 D) of the star, the star's colour is orange to red .
  • The star is calculated at being about 277.16 light years away from us. Distance

Location of Wolf 357

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 Wolf 357, the location is 10h 22m 14.0144725579 and +36° 49` 07.160440841 .

Radial Velocity and Proper Motion of Wolf 357

Proper Motion

All stars like planets orbit round a central spot, in the case of planets, its the central star such as the Sun. In the case of a star, its the galactic centre. The constellations that we see today will be different than they were 50,000 years ago or 50,000 years from now. Proper Motion details the movements of these stars and are measured in milliarcseconds. The star is moving -86.06 milliarcseconds/year towards the north and -198.18 milliarcseconds/year east if we saw them in the horizon.

Radial Velocity

The Radial Velocity, that is the speed at which the star is moving away/towards the Sun is 67.94000 km/s . When the value is negative then the star and the Sun are getting closer to one another, likewise, a positive number means that two stars are moving away. Its nothing to fear as the stars are so far apart, they won't collide in our life-time, if ever.

Physical Properties of Wolf 357

Wolf 357 Colour and Temperature

Based on the star's spectral type of K2 D , Wolf 357's colour and type is orange to red star. Based on the star's spectral, the stars temperature is between 3,700.00 and 5,200.00 degrees kelvin.

Distance to Wolf 357

The Parallax of the star is given as 11.76800 which gives a calculated distance to Wolf 357 of 277.16 light years from the Earth or 84.98 parsecs. It is about 1,629,319,808,431,569 miles from Earth.

The star is roughly 17,528,261.10 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 Wolf 357

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.
