Aug 10, 2023 · Compared to its proper motion, 3.5″ annually, the parallax of the Alpha Centauri system is a paltry 0.7687″ (+/- .003″), the greatest among all the stars, corresponding to a distance of 4.3 ...
Dec 29, 2014 · Facing North: Stars rotate counter-clockwise (right to left) Facing South: Stars rotate clockwise (left to right) Facing East: Stars rise in front, and set behind. Facing West: Stars rise behind, and set in front. In this video you can see how to locate Polaris (The North Star), and then see a time-lapse movie of the sky’s rotation.
Viewed from above the north pole, the earth is rotating counter-clockwise. For an observer on the earth, objects move from east to west (this is true for both northern and southern hemispheres). More accurately put, when looking north, objects in the sky move counter-clockwise. Though all objects rotate in the sky, the observed path stars make ...

Almost directly above the North Pole is the star Polaris. As the world turns on its axis, Polaris remains above the North Pole. If you had the misfortune of being at the North Pole in midwinter, Polaris would be a constant companion overhead. Imagine an alien looking down from Polaris at Earth. What would they see? They would see Earth’s Northern H...
Of course some stars do rise and set. The stars in the constellation Orion, the hunter, are almost directly above the Equator. From almost anywhere on Earth, the stars of Orion rise and then set roughly 12 hours later. However, our view of Orion depends on where we are. If you are in London, and looking at Orion when he’s highest in the night sky, ...
The world isn’t just turning on its axis, but also orbiting the Sun. This means we see different stars during the middle of the night at different times of year. During early January, the Sun is in the direction of the constellation of Sagittarius, while Gemini is visible at midnight. Six months later, the Earth has moved 180º around the Sun. Now t...
