Celestial coordinates
Celestial coordinates
Astronomical coordinate systems are organized arrangements for specifying positions of satellites, planets, stars, galaxies, and other celestial objects relative to physical reference points available to a situated observer (e.g. the true horizon and north cardinal direction to an observer situated on the Earth’s …

How do you find the south celestial pole?
The south celestial pole can be located from the Southern Cross (Crux) and its two “pointer” stars α Centauri and β Centauri. Draw an imaginary line from γ Crucis to α Crucis—the two stars at the extreme ends of the long axis of the cross—and follow this line through the sky.
Where is the north or south celestial pole in your sky?
The North Celestial Pole is 35∘ above your northern horizon. This tells you that you are at: latitude 35∘ N. In winter, Earth’s axis points toward the star Polaris.
What is the south Celestial point?
The South Celestial Pole is the point in the sky about which all the stars seen from the Southern Hemisphere rotate. You might wonder why this is important for building sundials. The Sun is also a star, so the Sun also rotates around the South Celestial Pole.
Where is the southern celestial hemisphere?
The southern celestial hemisphere, also called the Southern Sky, is the southern half of the celestial sphere, that is, it lies south of the celestial equator. This arbitrary sphere, on which seemingly fixed stars form constellations, appears to rotate westward around a polar axis due to Earth’s rotation.
Where is Polaris located?
Polaris, known as the North Star, sits more or less directly above Earth’s north pole along our planet’s rotational axis. This is the imaginary line that extends through the planet and out of the north and south poles.
Where in the sky is the Southern Cross?

How do you tell south from the Southern Cross?

If you travel downward toward the equator, you’ll be able to see more of the sky from the Southern Hemisphere’s perspective, while also losing more of what you’d normally see in the Northern Hemisphere. … Plus, because the Earth is orbiting the sun, you can see different parts of the sky depending on the time of year.
Is Polaris part of the Big Dipper?
Polaris lies at the end of the handle in the Little Dipper. Polaris can also be located by finding the Big Dipper, Ursa Major. To locate Polaris, all you have to do is to find the Big Dipper pointer stars Dubhe and Merak. These two stars outline the outer part of the Big Dipper’s bowl.
What is the nearest star to Earth after the Sun?
The two main stars are Alpha Centauri A and Alpha Centauri B, which form a binary pair. They are about 4.35 light-years from Earth, according to NASA. The third star is called Proxima Centauri or Alpha Centauri C, and it is about 4.25 light-years from Earth, making it the closest star other than the sun.
Can you see the North Star from the South Pole?
Currently Polaris is at a declination of a bit over 89 degrees, which means that no one south of 1 degree south latitude can see Polaris. That’s almost all of the Southern hemisphere, let alone the South Pole. Polaris won’t be the North Star forever, thanks to axial precession.
Can you see the Southern Cross from Panama?
Answer: You should be able to see the Southern Cross (the constellation Crux) in the southern sky from any location in Panama rising around 9PM, transiting around 1AM, and setting around 5AM local time.

How do you find south?
South will be halfway between 12 o’clock and the hour hand. In the Southern Hemisphere, align 12 o’clock on the watch with the sun, and the midway point between that and the hour hand will point north. When you are facing north, east is on your right and west is on your left.
Does the Southern Cross always point north?

At what altitude would you see the north celestial pole?
For all locations in the northern hemisphere, it is equal to your latitude. At the equator (0° N), the NCP is on the horizon, i.e., altitude = 0°. At the North Pole, the NCP is directly overhead, so the altitude = 90°.
Where do you have to be in order to see the north celestial pole on your horizon?
