ASTRONOMY EXAM 1 - the sky never does not look the same from any angle on earth -we always only see 180 degrees of the sky because the earth is in the way of seeing the rest. -you can see 360 degrees only at the equator over a 24 hr period -circumpolar stars travel in a circle in 24 hours -at the equator all stars are non circumpolar- travel above and below the horizon- above for 12 hrs and below for 12 hrs how to find the north star -use the pointer stars from the big dipper (top right of the bucket) and straight up to the last star on the tail of the little dipper= Polaris -whatever angle the NCP is that, that’s also your latitude -equator separates NP and SP, celestial equator follows same path as equator. NCP is always above NP and SCP is always below SCP. Horizon lays blocking the bottom of the earth from your view (below you) -earth is angled on its ecliptic path at 23.5 degrees - to be a planet a body must have a specific place by the sun and the area around it must be cleared of all rocky bodies. -stars that rise due east will be highest in the sky if you look south. Lowest in the sky in the north and will then set in the west. -new moon rises and sets with the sun, full moon does the opposite -moon rises and sets 50 minutes later each day waning new moon waxing full moon… CYCLICAL -plants always rise in eastern half of sky and set in west
