  • ADS 16402 A is not part of the constellation outline but is within the borders of the constellation.
  • Based on the spectral type (F8 E) of the star, the star's colour is yellow to white .
  • The star is calculated at being about 525.22 light years away from us. Distance

ADS 16402 A's Alternative Names

BD number is the number that the star was filed under in the Durchmusterung or Bonner Durchmusterung, a star catalogue that was put together by the Bonn Observatory between 1859 to 1903. The star's BD Number is BD+37 4734.

Location of ADS 16402 A

The location of the multiple star system 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 ADS 16402 A, the location is 22h 57m 45.9214 and +38° 40` 27.198 .

Radial Velocity and Proper Motion of ADS 16402 A

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 -41.92 milliarcseconds/year towards the north and 31.88 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 -3.44000 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 ADS 16402 A

ADS 16402 A Colour and Temperature

Based on the star's spectral type of F8 E , ADS 16402 A's colour and type is yellow to white multiple star system. Based on the star's spectral, the stars temperature is between 6,000.00 and 7,500.00 degrees kelvin.

Distance to ADS 16402 A

The Parallax of the star is given as 6.21000 which gives a calculated distance to ADS 16402 A of 525.22 light years from the Earth or 161.03 parsecs. It is about 3,087,571,618,503,496 miles from Earth.

The star is roughly 33,214,590.31 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 ADS 16402 A

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.
