Thora is asteroid #299 and also known as A890 TA as well as 1935 PC as well as 1939 PK. Thora was discovered by the Austrian astronomer Johann Palisa in 1890. Thora’s orbit is characterized by a semi-major axis of 2.43 Astronomical Units, an eccentricity of 0.06, a period of revolution of 1 387 days, and an inclination of 1.6 degrees.

The name Thora sounds like concerning the Jewish religion, but this impression is wrong. Thora is named after the god Thór from Norse mythology. He is the god of thunder. Having besides Jupiter also Donar, Taranis, Perun, ǂKá̦gára, Ukko, or Kadlu in the sky obviously still aren’t enough gods of thunder. Thór is the same god as Donar, so that he lends his name to two asteroids.

Donar is asteroid #2176 and also known as 2529 P-L, so Donar has got a much higher asteroid number than Thora. While all other asteroids named after deities of thunder show the gender of the deity, Thora is named in the manner of the old tradition and got a feminine suffix. Thór is a name used further in the north than Donar. The further north, the later Christendom arrived there. So the name Thór was longer in use and as I already explained while elaborating on the asteroid Odin the Norse deities changed and finally became militarized. These are the differences between Thora and Donar.

The meaning of Thora has to be derived from the differences with similar asteroids. The most striking difference is that Thora was overlooked when Donar got named. Thora is of a jovial and martial nature, but the same is true for Odin and Tyr. All asteroids with low asteroid numbers are named in the traditional manner with feminine names. So Thora’s main task should be to show that somebody or something is overlooked. But Thora still is a mighty god of thunder, so I have to wonder how a mighty god of thunder can be expected to react to being overlooked. Figuring this out means to understand the astrological force Thora.
