Planet Finding

Twinkle, twinkle little - planet? Nope planets don't twinkle like stars but that's only one key to finding them in the night sky. When you look up do you know if you're looking at a star or a planet? In this video we show you how to tell the difference between the two.

Thank you for your explicit explanation. But still a minor question, what you said about planets should be those in solar system. What about other planets in other galaxies?🤔 My guesstimate is those planets in other galaxies are too far away and won’t be visible to our eyes even if it might reflect certain photons?🤔🤔🤔 I could be wrong……🤔
