Mercury and VenusAs you look to the sky,
Mercury is always within 30 degrees from the Sun.
Venus is always within 60 degrees from the Sun.

All the other planets can be a full 180 degrees from the Sun. When you think about it, this just makes sense, because Mercury and Venus are the only two planets whose orbits are closer to the Sun than our Earth’s orbit is.
