The brightest asteroid 4 Vesta is the only one occasionally visible by naked eye. It will appear in opposition to the Sun on 2018 JUN 19 in northwestern Sagittarius west of Saturn. At magnitude +5.3 it will be shining nearly as brightly as it ever gets, since it will be near its perihelion while Earth will be near its aphelion.

Vesta currently rises in the late evening at magnitude +6.2, which is at the edge of naked eye visibility for sharp eyed observers under clear dark skies.

Photos and descriptions of Vesta would be welcome additions to this thread.

Here's a diagram I created of Vesta and Earth during the upcoming close encounter.
