Twinkle-twinkle little star…
Yup, you guessed it. A star does twinkle, so one that is a solid, unmoving light is a planet. However, planets don’t shine. Take Venus for example. It’s commonly known as the evening star, but if you really pay attention, Venus is just a brilliant pinpoint in the twilight. It glows and shines like that because the sun is shining on it.
Do you know how to tell if a star is close to Earth or if it’s going away from us?
Well, if you can’t it’s similar to the Doppler Effect (No, not Sheldon in his Halloween costume!). A star moving away from Earth will have a red glow about it, and a star moving toward us will have a blue tone.
If you’re a writer, watch the stars for inspiration. If you’re a reader, just imagine the worlds out there waiting to be discovered.
