Planets are visible (and look like stars, without the help of telescopes) almost all year, until their orbits carry them in line with the Sun. Which planets we can see depend mostly on what time of night we are looking, and where the planets are in the solar system on that night. Mercury is difficult to see because it is always very close to the Sun and orbits very quickly. Lucky for us, the orbits of the planets are very regular and predictable, so we can predict which ones are visible on which night, and where we can find them in the patterns of stars. Planetariums and orreries are very effective at modeling and displaying these patterns. Now that computer programs are becoming more accurate, prettier, and more frequently FREE, we can watch very detailed models of the night sky, and some of them even act like telescopes or space ships and let us get a very up-close look at the planets and other stellar objects. Plus all the pictures that have come from really cool telescopes like the Hubble, and are also available as free downloads.

How are planets distinguished from stars on the celestial?
planets appear to move
Are all the lights in the sky planets?
No, not all the lights in the sky are planets. Many of the visible points of light are stars, while others can be satellites, meteors, or artificial objects like airplanes. Planets can often be distinguished from stars because they usually shine with a steady light and can appear to move against the backdrop of stars over time.
It is now known that the celestial objects which appear to move backwards among the stars are?
The celestial objects that appear to move backwards among the stars are planets in our solar system. This phenomenon is called retrograde motion and is an apparent backward motion that occurs when Earth passes by these planets in their orbits.
What is the pattern called by which planets appear to move backward in the sky relative to the stars is?
The pattern by which planets appear to move backward in the sky relative to the stars is called "retrograde motion." This phenomenon occurs when Earth, on its orbit, passes by another planet, causing the other planet to appear to reverse its usual direction of motion against the background stars. Retrograde motion is an optical illusion resulting from the relative positions and movements of the planets in their orbits.
Do stars orbit planets or planets orbit stars?
Planets orbit stars.

planets appear to move
Why do planets appear to move through the background of stars?
Planets appear to move through the background of stars because they orbit the Sun at different speeds. As the Earth and other planets move in their orbits, their positions relative to the background stars change, causing them to appear to move across the sky. This is known as planetary motion.
Why do planets appear larger then stars?
because they're way closer than the stars
Why do planets appear brighter than stars?
Planets appear brighter than stars because they reflect more sunlight and have larger apparent sizes in the night sky compared to distant stars. Stars emit light due to nuclear fusion in their cores, while planets reflect light from the Sun, making them appear brighter to us on Earth.
Are all the lights in the sky planets?
No, not all the lights in the sky are planets. Many of the visible points of light are stars, while others can be satellites, meteors, or artificial objects like airplanes. Planets can often be distinguished from stars because they usually shine with a steady light and can appear to move against the backdrop of stars over time.
The planets appear to move through the background of stars because?
the planets orbit the Sun at varying speeds, causing them to appear to move against the fixed backdrop of stars as seen from Earth. This apparent motion is due to the Earth's own movement around the Sun, which creates the illusion of planets traversing the sky over time.
It is now known that the celestial objects which appear to move backwards among the stars are?
The celestial objects that appear to move backwards among the stars are planets in our solar system. This phenomenon is called retrograde motion and is an apparent backward motion that occurs when Earth passes by these planets in their orbits.
Where is the largest sunspot on Neptune?
Sunspots, as the name suggests, appear on the Sun or on stars - not on planets.
When you view the stars and planets in the night sky they all appear to move on a great?
They appear to move on a great hollow sphere
Why do planets change their position with respect to stars?
Because the Earth and all the planets move in orbits round the Sun, while the stars appear to be fixed if we disregard the Earth's daily rotation.
Are the stars planets or are they the same as the sun?
The night time stars are suns, so distant they appear as points of light. Note that the planets Mercury, Venus, Mars, Jupiter, and Saturn can be seen without a telescope and can be mistaken for stars.
Planets appear as stars?
Well, because they are so far away, they appear to be the same shape and colour as a star because they are so far away you cannot work out the details on the planet, in comparison to a star. Hope I've helped??
