... would make 8.5 (but obviously you can’t have a half throw!). The square root of 8.5 is 2.9 so one should expect to see a number of throws made in the range of 8.5-2.9 to 8.5+2.9 or 5.6 to 11.4 so making only 6 throws wouldn’t be so unusual.

... years away. So how far away is 1 light year? It refers to the distance that a photon of light travels in a 1 year period. The speed of light is 300,000km per second, or 1,080 million km per hour (about 670 million miles per hour) so 1 light year equates to a distance of 9,460,000,000,000 km – so a u ...

Ursa Major



Ursa Major /ˈɜrsə ˈmeɪdʒər/ (also known as the Great Bear and Charles' Wain) is a constellation in the northern celestial hemisphere. One of the 48 constellations listed by Ptolemy (second century AD), it remains one of the 88 modern constellations. It can be visible throughout the year in most of the northern hemisphere. Its name, Latin for ""the greater (or larger) she-bear"", stands as a reference to and in direct contrast with Ursa Minor, ""the smaller she-bear"", with which it is frequently associated in mythology and amateur astronomy. The constellation's most recognizable asterism, a group of seven relatively bright stars commonly known as the ""Big Dipper"", ""the Wagon"" or ""the Plough"" (among others), both mimicks the shape of the lesser bear (the ""Little Dipper"") and is commonly used as a navigational pointer towards the current northern pole star, Polaris in Ursa Minor. The Big Dipper and the constellation as a whole have mythological significance in numerous world cultures, usually as a symbol of the north.The third largest constellation in the sky, Ursa Major is home to many deep-sky objects including seven Messier objects, four other NGC objects and I Zwicky 18, the youngest known galaxy in the visible universe.
