Tyr is asteroid 4092 and also known as 1986 TJ4. Tyr was discovered by the Danish astronomer Poul B. Jensen at Brorfelde. An “asteroid moon”, that orbits around Tyr, was discovered last year and doesn’t have a name yet, but only the designation S/2020 (4092) 1. Besides this is Tyr a common Main Belt Asteroid.

Tyr is named after the Norse god Týr. Germanic tribes knew him as Tiu or Ziu. He was their main god until Wotan became their main god. Ziu has the same etymology as Zeus. The same word is also the Latin deus, which means god (Diēspiter = Jupiter = god the father), or Sanskrit deva (देव​), which also means god, or Dievs, which is the name of the god of the sky and main god in Baltic mythology. Ziu is also the god of the sky. Additionally he is the god of justice. He keeps everything in balance and this is, according to Norse mythology, also necessary with the sky for preventing it from falling down. When the Romans advanced due to their military superiority and the Germanic tribes retreated, Germanic gods became more militarized. So the Scandinavian names represent more militarized gods than the Germanic names, thus sometimes giving the impression that many Norse gods are gods of war. Týr is, besides the god of justice and the god of the sky, the god of war. Týr presides over these three fields.

Týr also has a tale. Unlike in Greek or Roman or Egyptian mythology, the Sun and the Moon are in Norse mythology not gods, who drive chariots over the sky. They are divine too, but they are horses with bright shining fur. Because they are horses, so they fear predators. Europe isn’t haunted by dangerous animals, so wolves have to serve as the dangerous predators in fairy tales as well as in Norse mythology. Of the most dangerous three of them is one hunting the Sun and sometimes causing solar eclipses when he gets and devours the Sun, the other is hunting the Moon and sometimes causing lunar eclipses when he gets and devours the Moon. But the third, Fenrir or Fenriz with name, is able to devour the world. The Norse gods decided to avoid this by chaining Fenrir. But he broke free. The gods chained him again, but he broke the chains and freed himself again. Then the dwarfs of Niðavellir made a magical binding and named it Gleipnir. This was able to hold Fenrir, but the mighty wolf didn’t trust the gods anymore, so they weren’t able to bind him. Until Týr agreed to give himself as a pawn, while the other gods would only test whether Gleipnir could really do what the dwarfs guaranteed. So Týr put his right hand in Fenrir’s mouth, the gods did bind Fenrir and Fenrir bit off Týr’s hand in revenge. From then on Týr wasn’t able to fight on the battlefields anymore as the other Norse gods did. But Týr is still the god of war, by the Romans believed to be the counterpart of Mars, so Týr gained in exchange the power to decide the outcome of battles. So Týr is the god of justice as well as the god, who decides the outcome of battles. So battles bring justice and this belief is still hardwired in all persons of Germanic descendance, whether they doubt this influence or not. Norse mythology knows exactly how the world ends and these events are called Ragnarök. During this Týr fights the hellhound Garm, that is by some people believed to be the wolf Fenrir. Garm sees Týr as his enemy at least and both die in this battle. That Norse gods are able to die, although they are immortal, is probably due to Christendom replacing the old faith.

Justice, the sky, and war are the subjects of Tyr. What are the subjects of Tyr is clearer defined than the subjects of any other astrological force of the Norse mythology. Tyr has traits of Jupiter as well as of Uranus as well as of Mars. The classic planets always have the final say. So they have always to be considered when interpreting Tyr. His own stance is of course given by positions in the signs and the formed aspects.
