An experienced astronomer will recognize the stars and the constellations; he would either know from experience, for the brighter stars, or be able to look it up in a reference guide for the dimmer stars. Anything that isn't part of the pattern of fixed stars is either a planet, an asteroid or a comet. A little observation with a telescope will tell you which.
For the rest of us, I recommend a planetarium program called Stellarium, available for free online at stellarium.org. This is the program that I use whenever someone asks a question like this. :-)
Celestial bodies seen at night are typically called stars, planets, moons, and sometimes meteors or comets. These objects are visible in the night sky when the sun has set and the sky is dark enough for them to be seen.
The celestial equator is an imaginary line in the sky that is used to measure the motion of celestial objects. It is a projection of Earth's equator into space and helps astronomers locate objects in the sky based on their declination.
The positions of moons, stars, and planets in the night sky are determined by their orbits and the relative motion of celestial bodies. As Earth rotates on its axis and orbits the Sun, we observe different celestial configurations throughout the night and across seasons. Additionally, the gravitational interactions between these bodies influence their paths, leading to phenomena such as retrograde motion in planets. Overall, the night sky is a dynamic display shaped by the complex movements of celestial objects.
There are quite a few astronomy programs out there that you can use to identify a planet in the sky above you. I use WorldWide Telescope from Microsoft. You just set your viewing location and it shows you what you can see from that spot.
The moon is the closest heavenly body to the earth and because of its relatively high albedo it reflects a lot of the light falling on it hence it is the brightest object in the night sky. Similar reasons also apply to Venus, which is also a very bright object.
When you look at the moon, you see a rocky celestial body that reflects sunlight, appearing as a bright, round object in the night sky.
The night sky is mapped using celestial coordinate systems such as the equatorial coordinate system, which uses declination and right ascension to pinpoint the location of celestial objects. Astronomers use tools like star charts, telescopes, and computer software to create detailed maps of the night sky, allowing them to navigate and identify objects in space. These maps help astronomers locate and study stars, planets, galaxies, and other celestial bodies with accuracy.
They are objects in the sky
A constellation is a group of stars perceived as forming a particular pattern or shape when viewed from Earth. It helps astronomers to easily identify and locate celestial objects in the night sky. Modern definitions also include areas of the sky defined by the International Astronomical Union for the purpose of mapping and organizing the night sky.
To identify the North Star in the night sky, look for the brightest star in the constellation Ursa Minor, also known as the Little Dipper. The North Star, also called Polaris, appears almost stationary in the sky and is located close to the north celestial pole. It can help you determine true north for navigation purposes.
Astrophysics is the love of the night sky/stars/celestial space
Celestial body is only a general name for an object in the sky, particlarly applied to the night sky (but including the Sun). The moon, stars, planets, etc., are considered celestial bodies. Most of them were identified by the ancients; in modern times the more distant planets from Earth were discovered by use of more powerful telescopes.

Just like every other celestial object, the stars and their apparent patterns move from east to west in the sky as time goes on.
