Jupiter actually appears yellow, not silvery-white. And it’s brightness around the year doesn’t vary that much. But being opposite the sky as the sun, it’s visible all night.
Last week I saw a very bright planet. Not being up on things, not sure which one.
Got out the binoculars 10x, and saw it and 4 moons. I’ll bet that’s Jupiter. But are those really its moons?
Checking the web, Yes.
