Click on the labels directly above to view the Best Planet Conjunctions of 2021, that is, when two major planets appear close in the sky.  Note that these views are geocentric—i.e. from Earth's center—so the apparent angular distances between the planets may be very slightly different from those you'll see from your own location on Earth's surface.  The views above all highlight events where planets appear less than 1° (one degree) apart!   In fact, these "close apparent approaches" are all less than half that, so they will appear closer than one Moon diameter!

Here's a list of  More 2021 Planet Conjunctions.  The ones involving Uranus and Neptune require very clear, dark skies to get any serious chance at viewing them.  Uranus is visible just barely at the limit of what can be seen by the naked eye, and viewing Neptune requires at least a very good pair of binoculars.  Even so, a pretty capable telescope is desirable for both on most occasions.

Simulator Image Notes:  1) Fields of View are measured horizontally.  2) Eclipse shadows of planetary moons are not displayed.  3) Light-Travel Time is not included in calculated times.   4) Planet of focus (at center of simulator image) is viewed with its local north "upward", i.e. in the 12:00 midnight direction.  5) Simulator expresses the phase (where applicable) as the absolute value of the phase angle.
