Because of the orientation and tilt of their orbits, the eight major planets of the Solar System can never come into perfect alignment. The last time they appeared even in the same part of the sky was over 1,000 years ago, in the year AD 949, and they won’t manage it again until 6 May 2492.
Why are the stars flickering tonight 2020?
The reality is that every star in the sky undergoes the same process as Capella, to produce its colorful twinkling.

What do satellites look like in the night sky?
The satellites don’t emit any light themselves, said Samantha Lawler, an astronomer at the University of Regina. Instead, they’re visible because they reflect sunlight. “It’s like a train of stars moving together in a line.
What are the moving objects in the night sky?
These lights are actually satellites, launched into space by the U.S. company SpaceX, run by South African entrepreneur Elon Musk. And they’re a bit controversial. The satellites are part of something called Starlink.
What color is Venus?

Why is Venus so bright?
Venus is so bright because its thick clouds reflect most of the sunlight that reaches it (about 70%) back into space, and because it is the closest planet to Earth. Venus can often be seen within a few hours after sunset or before sunrise as the brightest object in the sky (other than the moon).

What happens when all planets align?
