you can differentiate Star and Planet by it's color or steadiness of light.
"Star generates their own light whereas planets only reflect light".
The visible planets are Mercury, Venus , Mars, Jupiter and Saturn. Venus and Jupiter are very bright , especially venus a bright white color and Jupiter a golden white - though both of them are stunning. Mars is close to orange ! saturn , a pale yellow and Mercury , a greyish white color which is hardest to spot than all .
The unique thing about Venus is , unlike other planets they can't be found at any time . they are seen just before sunrise or just after sunset, they never appear fully on the night.They are called as Evening or Morning stars ( although they are not stars) .The main thing to remember is that stars twinkle whereas planets won't .
There are so many things to learn from universe..Be curious, look up and stay amazed !
