- Light-year (Wikipedia)
A light-year, alternatively spelled light year (ly), is a unit of length used to express astronomical distances and is equal to exactly 9,460,730,472,580.8 km (Scientific notation: 9.4607304725808 × 1012 km), which is approximately 5.88 trillion mi. As defined by the International Astronomical Union (IAU), a light-year is the distance that light travels in a vacuum in one Julian year (365.25 days). Because it includes the word “year”, the term is sometimes misinterpreted as a unit of time.
- Hammurabi (Wikipedia)
Hammurabi (/ˌxæmʊˈrɑːbi/; Old Babylonian Akkadian: 𒄩𒄠𒈬𒊏𒁉, romanized: Ḫâmmurapi;[a] c. 1810 – c. 1750 BC), also spelled Hammurapi, was the sixth Amorite king of the Old Babylonian Empire, reigning from c. 1792 to c. 1750 BC. He was preceded by his father, Sin-Muballit, who abdicated due to failing health. During his reign, he conquered the city-states of Larsa, Eshnunna, and Mari. He ousted Ishme-Dagan I, the king of Assyria, and forced his son Mut-Ashkur to pay tribute, bringing almost all of Mesopotamia under Babylonian rule.
