All January you’ll find Venus and Saturn in the southwest for the first couple of hours after sunset, while Jupiter shines brightly high overhead and Mars rises in the East. Uranus and Neptune are there too, but you’d need a telescope to see them. This is because all the planets are currently on the same side of the sun.
All the planets in the solar system, including Earth, orbit the sun on approximately the same plane, and are also all going the same direction. This is an opportunity to visualize the orbital disc of the sun with all its planets and moons, asteroids, comets, and debris. That’s some really big geometry. I find it delightful to contemplate.
