* Stars: These are giant balls of hot gas that emit their own light. They are the most common source of bright lights in the night sky.
* Planets: These are celestial bodies that orbit a star. They don't emit their own light, but reflect light from their star. Some planets, like Venus, can appear very bright.
* The Moon: Our moon reflects sunlight, making it appear as a bright, shining light in the sky.
* Satellites: These man-made objects orbit Earth and can be bright enough to see from the ground.
* Meteors (Shooting Stars): These are small pieces of space debris that burn up as they enter Earth's atmosphere, creating a bright streak of light.
To know for sure what you're looking at, you'll need to consider a few things:
* How bright is it? Planets are usually brighter than stars.
* Does it move? Satellites move across the sky, while stars and planets seem to stay in the same place.
* Is it steady or twinkling? Planets usually appear steady, while stars twinkle due to the Earth's atmosphere.
