How many circumpolar stars would you see if standing on the equator?
Standing on the equator, you would not see any circumpolar stars. Circumpolar stars are those that never dip below the horizon, and they can only be seen from latitudes above a certain threshold, typically around 25 degrees (North or South) or higher. The closer you are to the poles, the more circumpolar stars you can see.
What range of declination makes stars appear circumpolar?
Subtract your latitude from 90° and that will give the the decollation of circumpolar stars. In northern New Zealand, my latitude is 35°. If I subtract that from 90°, I get 55°. So stars with Declination great than 55° are circumpolar for me.
Are more stars circumpolar at the North Pole or in the US?
The simple answer: "at the North Pole". A more detailed answer: ALL stars are "circumpolar" in the sense that they seem to rotate around points above the Earth's poles (called the "celestial poles"), as the Earth turns. But we use that word to mean stars that are close enough to the poles of the sky so that they don't rise or set at the observer's latitude. By that definition, the stars that are 'circumpolar' from any location are those that have "declinations" not less than 90 degrees minus your latitude. Declination is a measure of how far a star is from being above the Earth's equator. Polaris, the "pole star", has a declination of nearly 90 degrees, and is almost exactly above the Earth's North Pole. The greatest possible geographic latitude is 90 degrees, at either pole, so that's where the greatest possible amount of sky is 'circumpolar'. At the north pole, half of the entire sky is visible at any time the sky is clear, during the six months of "night". No star ever rises, and none ever sets. Each one just goes around and around the sky, parallel to the horizon and never moving higher or lower in the sky. And you never see anything that's in the OTHER half of the sky. At the other extreme ... for an observer standing on the Equator, nothing in the sky is circumpolar, and you can see every celestial object sooner or later.
What constellations are visible to earth during all 12 months of the year these are the circumpolar constellations?
There are dozens, but it would depend on where you live. For example, if you live in the Arctic or Antarctic, you can't see ANY stars at midsummer, when the Sun is up all the time.
When circumpolar stars can be seen?
Circumpolar constellations are those that never set below the horizon. The further north (or south) one travels, the more constellations are circumpolar. Where I live, above the 45th parallel, most of the Big Dipper stars are circumpolar, but Arcturus is not, and the constellation of Orion sets below the horizon in the summer. Equatorial constellations are those that pass directly overhead when one is between the tropics of Cancer and Capricorn. I believe these are primarily the 13 constellations of the zodiac.
How can you if a particular star is circumpolar from a certain latitude?
To determine if a star is circumpolar from a certain latitude, you can compare the star's declination to the observer's latitude. A star is circumpolar if its declination is greater than or equal to the observer's latitude. For example, if you are at a latitude of 60°N, any star with a declination of +60° or higher will be circumpolar, meaning it never sets below the horizon. This can be visually confirmed by observing the star's position in the sky over time; circumpolar stars will appear to move in circles around the North or South celestial pole without dipping below the horizon.
Is Pisces circumpolar?
Circumpolar constellations are those that, from the viewer's latitude, never set. Any constellation found in the zodiac is not circumpolar. These are seasonal. Pisces appears in the Spring in the Southern hemisphere and in Autumn in the Northern hemisphere.
What rises in the east and sets in the west for an observer in New York?
Most natural celestial objects do this; exceptions would be any fixed star that is 'circumpolar'-- they are close enough to the celestial poles that they never appear to dip below the observer's horizon. Which stars are circumpolar depends on the latitude of the observer.
What is the season to see Cassiopeia?
In the northern hemisphere, it can be seen at any time of year, as it is a circumpolar constellation.
Did galen have any problems with dissection?
Yes. He couldnt find the penis
What not to do when you have the plague?
You would not want to have contact with any other people, as you might infect them. Today the few cases of plague that occur are treated with antibiotics.
Was a Christmas for poor Victorians good?
