Hassaleh - Iota Aurigae - HD31398 - HIP23015

Hassaleh (Iota Aurigae) is an orange to red luminous giant star that can be located in the constellation of Auriga. Iota Aurigae is the Bayer Classification for the star. HIP is the reference name for the star in the Hipparcos Star Catalogue. The Id of the star in the Henry Draper catalogue is HD.

Location of Hassaleh

The location of the star in the galaxy 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 from celestial equator. The Declination is how up or down compared to the celestial equator and is expressed in degrees. For Hassaleh, the location is 04h 56m 59.62 and +33 d 09 ` 58.1 .

Physical Properties/View of Hassaleh

Hassaleh has a spectral type of K3IIvar. This means the star is (K) orange to red coloured (II) luminous giant. Hassaleh lies at a distance of 512.03 light years away from our Sun and our planet Earth or to put it another way, 156.98 parsecs away from the Sun.

Hassaleh has an apparent magnitude of 2.69 which is how bright we see the star from Earth. Apparent Magnitude is also known as Visual Magnitude. Hassaleh has an absolute magnitude of -3.29 which is the apparent magnitude of an object if it were 32.6 light years away or 10 parsecs from Earth. 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. The stars temperature has been calculated at between 3700 and 5200 based on the Class Type and lookup at Wikipedia-Stellar Classification

Meteor Showers Radiating from near Hassaleh

The Nov. Iota Aurigids Meteor Shower radiants from a point near this star. The meteor shower runs typically between 1 Nov- 23 Nov with a peak date of 15-Nov. The speed of a meteor in the shower is 36 Km/s. The amount of meteors predicted to be seen per hour (Zenith Hourly Rate) is 36.

Source of Information

The source of the information came 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.
