They look like points of light. On first sight, a planet might be confused with a star (a very bright star, in the case of Venus, Jupiter, and sometimes Mars).
Planets shine brightly and do not flicker while stars do not shine as bright (usually) and they always flicker, or sparkle.

Mercury, Venus, Mars, Jupiter, Saturn, and Uranus. Neptune looks like a star too, but is only visible in telescopes.
Uranus can be seen with the naked eye on really dark nights, but it is quite faint, which is why no one discovered it until the late 18th century.
The reason ancient Greeks knew the first five were NOT stars is because their position changes with respect to that of the background stars.
They look just like stars excpet that the nearer (brighter) ones do not twinkle as much. If you look at a planet repeatedly for several nights it can be seen to change its position slightly relative to the stars.

Pluto
Because the stars emit light. The closer they are, the brighter. Also planets reflect the light off of the stars, so they also look like stars.
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.
Venus is a planet. It is referred to as a star because it is the brightest object in the night sky other than the moon. Planets look like stars.
There are several bright stars. Planets move around the Ecliptic, covering 13 constellations or so. Note that planets look like stars, but are not currently considered stars. Also note that some of the planets look brighter (to us) than any real star. Other than planets, the brightest stars are the Sun (also changes through the constellations of the Ecliptic), Sirius (Canis Major), Canopus (Carina), and Toliman (Centaurus).

why do the planets look like stars
Planets but the look like stars
Because the stars emit light. The closer they are, the brighter. Also planets reflect the light off of the stars, so they also look like stars.
Firstly, planets are way way smaller than the stars! That's because you can see stars in the night but never planets. Also stars produce nuclear energy in their core so they give thermal ( heat ) energy. Also stars have more gravity than planets.
there are certain times when those planets... like venus..... are in an alignment with the sun and the sun's light... letting those planets REFLECT the same light the stars do...... the sun's light...... without the sun's light..... the stars too would be dark ^^
No, because sometimes planes, helicopters, or far off planets look like stars but aren't.
Yes and no because when you look up in the sky some of those stars are planets but techinacally they aren't stars.
The auroras look like poles of light curtains in the night sky and not like the light branches of light or the planets of light.
Stars are not planets. They are like our sun and may or may not have planets orbiting around them. Stars are hot and the heat makes them look like bright lights in the sky on a clear night. Planets do not create very much, if any, visible light and are much harder to see because they only reflect the light from stars.
sometimes other planets can look like stars, but a star in itself is just a star. No. Stars are things like our Sun. While you may occasionally see some very close planets in the sky, most of the lights you see will not be planets.
Astronomy covers a lot of areas like the study of stars, galaxies, nebulae, clusters, asteroids, comets and of course planets. If you go out and look at the night sky, if you know where to look, you will see some of the planets. Currently, in February 2009, Venus is visible as a very bright object in the west after sunset and Saturn is visible through much of the night near the constellation of Leo. Just looking at them, or when we are specifically observing or studying planets we are engaging in astronomy.
