178 Belisana is a stony background asteroid from the inner regions of the asteroid belt , approximately 38 kilometers (24 miles) in diameter. It was discovered on 6 November 1877, by Austrian astronomer Johann Palisa at the Austrian Naval Observatory in today's Croatia.[ 1] S-type asteroid has a rotation period of 12.32 hours and a rather spherical shape.[ 6] Belisama (Belisana).[ 2]
Orbit and classification
Belisana is a non-family asteroid from the main belt's background population .[ 4] [ 5] inner main-belt at a distance of 2.4–2.6 AU once every 3 years and 10 months (1,409 days; semi-major axis of 2.46 AU). Its orbit has an eccentricity of 0.04 and an inclination of 2° with respect to the ecliptic .[ 3]
Physical characteristics
Belisana has been characterized as a common, stony S-type asteroid in both the Tholen and SMASS classification .[ 3]
Rotation period
Photometric observations of this asteroid from multiple observatories during 2007 gave a light curve with a period of 12.321 ± 0.002 hours and a brightness variation of 0.10 ± 0.03 in magnitude . This is in agreement with a study performed in 1992. However, it is possible that the light curve may have a period of 24.6510 ± 0.0003 hours; it will require further study to exclude this solution.[ 13]
Diameter and albedo
According to the surveys carried out by the Infrared Astronomical Satellite IRAS , the Japanese Akari satellite and the NEOWISE mission of NASA's Wide-field Infrared Survey Explorer , Belisana measures between 35.81 and 42.09 kilometers in diameter and its surface has an albedo between 0.214 and 0.2438.[ 7] [ 8] [ 9]
The Collaborative Asteroid Lightcurve Link derives an albedo of 0.2026 and a diameter of 35.50 kilometers based on an absolute magnitude of 9.6.[ 6]
Naming
This minor planet was named after the goddess Belisama (or Belisana) from Celtic mythology , meaning "queen of heaven", the most warlike goddess among British Celts , and equivalent to the goddesses Athene or Minerva. The official naming citation was mentioned in The Names of the Minor Planets Paul Herget in 1955 (H 22 [ 2]
