The basic rule of thumb is that if your latitude and the star's declination are less than 75 degrees apart, the star will be visible for at least part of the year.
Why 75 degrees and not 90 degrees? Well, on a theoretical spherical world without any atmospheric distortions, that would be correct. But the Earth isn't spherical; it has these bumps called "mountains", and a thick atmosphere that obscures low-elevation stars, and it can be worse if there is any light pollution on the horizon. (This is one of the reasons why astronomical observatories are generally built on mountain tops away from city lights.) Against a dark sky and a sea horizon, you would probably be safe calculating to an 85 degree difference, but only if it were a bright star.
I live near Sacramento, CA, at about 38N. So any star in the northern half of the sky is certainly visible. Going by my 75 degree rule, I ought to be able to see stars that are as far south as 37S declination, which you can look up in the Nautical Almanac or online. (See the link below, and look for the "Stars" column in the center column for declinations.)
So, I ought to be able to see the star Fomalhaut at 29.S, but not Alpha Centauri at 61S. However, from my house I would not be able to see Fomalhaut - because the city lights and tall trees to the south would probably block my view. If I really wanted to see Fomalhaut, I'd need to drive down into the farmlands south of town where I would have an unobstructed view.
What else can I help you with?
Why do you think scientists are able to predict where in the night sky a planet will be visible?
Scientists can predict the position of planets in the night sky using mathematical models based on our understanding of planetary motion. By taking into account the planet's orbit, speed, and gravitational interactions with other celestial bodies, scientists can accurately calculate its position at any given time. This information allows them to forecast when and where the planet will be visible from Earth.
How many stars are visible at night?
On a clear night, around 2,500 stars are visible to the naked eye from any given spot on Earth. The number can vary slightly depending on light pollution and atmospheric conditions. With a telescope, millions of stars become visible.
You can see all the energy given off the sun with your eyes true or false?
False. While our eyes can perceive sunlight in the visible spectrum, the Sun emits energy in a wide range of wavelengths, including ultraviolet and infrared light, which are not visible to the human eye.
What is long wavelength radiation given out by stars?
Long wavelength radiation given out by stars is typically in the form of infrared radiation. This type of radiation has longer wavelengths than visible light and is emitted by stars as a product of their high temperatures. It is important for studying the properties and evolution of stars.
How many rainbows are possible at a time?
At any given time, only one primary rainbow can be visible in the sky. A secondary rainbow can also form outside the primary rainbow, but it is usually fainter and has its colors reversed. Therefore, a maximum of two rainbows can be visible at the same time under the right conditions.
What country is located at 105 degrees latitude and 30 degrees latitude?
-- There is no such latitude as '105 degrees'. The greatest possible latitude is 90 degrees, whether it's north or south. -- No place on Earth has two different latitudes. -- When you give the latitude of a place, you must also reveal whether that latitude is a north or south latitude. Otherwise, even though you think that you've given the latitude, we don't even know the latitude of the place. -- In order to describe a unique location, you must also give its longitude.
What three pieces of information do GPS systems calculate for a given location?
latitude, longitude, altitude, and velocity vector. OOPS, that was 4 wasn't it?
Is light visible in the given scenario?
In the given scenario, light is visible.
Do you look at the lines of latitude or the lines of longitude first when you are finding the coordinates?
It does not matter whether you look at the lines of latitude or longitude first. Usually coordinates are written latitude, then longitude. Good luck!
When given latitude and longitude coordinates which is given first?
Typically, latitude is given first followed by longitude when providing coordinates. Latitude measures the north-south position, while longitude measures east-west. So the order is latitude, longitude. For example, 40.7128° N, 74.0060° W represents the latitude and longitude coordinates for New York City.
