236 G. Puppis's Alternative Names

HIP39035 is the reference name for the star in the Hipparcos Star Catalogue. The Id of the star in the Henry Draper catalogue is HD66005.

The Gould star designation is one that was designed by American astronomer, Benjamin Apthorp Gould. Gould stars are predominantly in the Southern and Equatorial constellations but do appear in northern constellations such as Bootes and Orion. The star has the designation 236 G. Puppis. There are no stars with a Gould designation in Ursa Major for example.

Location of 236 G. Puppis

The location of the subgiant 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 236 G. Puppis, the location is 07h 59m 12.31 and -49° 58` 36.7 .

Physical Properties of 236 G. Puppis

236 G. Puppis Temperature and Colour

Based on the star's spectral type of B2IV-V , 236 G. Puppis's colour and type is blue subgiant star. The star has a B-V Colour Index of -0.15 which means the star's temperature is about 13,674 Kelvin. The temperature was calculated using information from Morgans @ Uni.edu.

236 G. Puppis Radius

236 G. Puppis estimated radius has been calculated as being 3.52 times bigger than the Sun. The Sun's radius is 695,800km, therefore the star's radius is an estimated 2,452,520.70.km. If you need the diameter of the star, you just need to multiple the radius by 2. The figure is derived at by using the formula from SDSS rather than peer reviewed papers. It has been known to produce widely incorrect figures.

236 G. Puppis Apparent and Absolute Magnitudes

236 G. Puppis has an apparent magnitude of 6.35 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 -1.63 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 236 G. Puppis

Using the original Hipparcos data that was released in 1997, the parallax to the star was given as 2.54000 which gave the calculated distance to 236 G. Puppis as 1284.11 light years away from Earth or 393.70 parsecs. If you want that in miles, it is about 7,548,801,627,958,805.44, based on 1 Ly = 5,878,625,373,183.61 miles.

Travel Time to 236 G. Puppis

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.

Source of Information

The source of the information if it has a Hip I.D. is from Simbad, the Hipparcos data library based at the University at Strasbourg, France. Hipparcos was a E.S.A. satellite operation launched in 1989 for four years. The items in red are values that I've calculated so they could well be wrong. Information regarding Metallicity and/or Mass is from the E.U. Exoplanets. The information was obtained as of 12th Feb 2017.
