Where is Mercury right now?
Mercury is currently about 204,973,873 kilometres from Earth, or 1.37 astronomical units. In the sky it is 2 degrees from the Sun and lost in the glare.
This page is about where Mercury is. For the planet itself, its size, its day, its moons and a photograph, see Mercury.
Mercury is the hardest of the five naked-eye planets to catch, and the figure above is the reason. It never gets further than about 28 degrees from the Sun, and often less than 20, so it is only ever visible in twilight, low down, for a week or two at a time before it swings back into the glare. Today it is 2 degrees out, and it reaches its highest point at nearly the same moment as the Sun.
It goes round in 88 days and turns on its axis three times for every two of those orbits. That 3:2 resonance gives it a solar day of about 176 Earth days: sunrise to sunrise takes two Mercury years.
Nothing about the surface moderates any of this. There is no atmosphere to hold heat or spread it, so the ground runs to roughly 430°C in daylight and falls to about -180°C at night, the widest swing on any planet. Radar has found what appears to be water ice sitting in polar craters whose floors have never seen the Sun.
One spacecraft has ever orbited it: MESSENGER, from 2011 to 2015. Mariner 10 managed three flybys in 1974 and 1975 and nothing else went near it for thirty years. BepiColombo, flown jointly by ESA and JAXA, has spent since 2018 shedding speed across nine planetary flybys and is due to enter orbit in November 2026.
