WebIf m1 and m2 are the magnitudes of two stars, then we can calculate the ratio of their brightness ( b 2 b 1) using this equation: m 1 − m 2 = 2.5 log ( b 2 b 1) or b 2 b 1 = 2.5 m 1 − m 2. Here is another way to write this equation: b 2 b 1 = ( 100 0.2) m 1 − m 2. Let’s do a real example, just to show how this works. Web18 jan. 2013 · Scientists working with the Hipparcos satellite measured Polaris's distance by taking its trigonometric parallax; that is, how, over a period of months or years, the star moves across our line of sight in relation to other objects in the sky. Polaris, the team calculated, was 434 light-years away. But last year, Turner challenged that figure.
WebIn this coordinate system, an observer at some latitude would observe that any star reaches a maximum altitude in the sky. That maximum altitude is equivalent to the latitude of the observer and is known as declination .Thus if you were on a sailing ship and had a list of declinations of brightstars and measured when those stars reached their maximum … WebPolaris, the North Star has been calculated to be about 323 light years from our Sun. This is a reasonably new calculation as it used to be considered to be 434 light years away. BUT, John Bingamon added a comment once again putting the distance at 445 light years.

Web24 aug. 2024 · Merak and Dubhe are also known as the 'Pointers', because they point to Polaris, the North Star. Once we’ve found the Plough, all we need to do is draw a line between Merak (β UMa) and Dubhe (α UMa), the two stars at the end of the Plough’s blade, and then out through the blade’s top. The next fairly bright star we see is Polaris.
WebIn geography, the antipode (/ ˈ æ n t ɪ ˌ p oʊ d, æ n ˈ t ɪ p ə d i /) of any spot on Earth is the point on Earth's surface diametrically opposite to it. A pair of points antipodal (/ æ n ˈ t ɪ p ə d əl /) to each other are situated such that a straight line connecting the two would pass through Earth's center. Antipodal points are as far away from each other as possible. chippin liability shiftWeb2 dec. 2024 · Simple math and the Pythagorean Theorem tells us that the sun is around 3000 miles above the Earth.
