Only one asteroid, 4 Vesta, which has a relatively reflective surface, is normally visible to the naked eye in dark skies when it is favorably positioned. Rarely, small asteroids passing close to Earth may be briefly visible to the naked eye. [ 20 ]
On Sunday, the asteroid will reach a peak brightness of magnitude 9.4, which is too faint for the naked eye but visible through entry-level binoculars or a backyard telescope, according to ...
If you miss out, mark your calendar for April 13, 2029, when an asteroid called Apophis will fly by Earth and will be visible to the naked eye from parts of Europe, Africa and Asia.

In astronomy, the naked eye may be used to observe celestial events and objects visible without equipment, such as conjunctions, passing comets, meteor showers, and the brightest asteroids, including 4 Vesta. Sky lore and various tests demonstrate an impressive variety of phenomena visible to the unaided eye.
[43] [44] It will be the closest asteroid of its size in recorded history. On that date, it will become as bright as magnitude 3.1 [45] (visible to the naked eye from rural as well as darker suburban areas, visible with binoculars from most locations). [46] The close approach will be visible from Europe, Africa, and western Asia.

Its size and unusually bright surface make Vesta the brightest asteroid, and it is occasionally visible to the naked eye from dark skies (without light pollution). In May and June 2007, Vesta reached a peak magnitude of +5.4, the brightest since 1989. [119] At that time, opposition and perihelion were only a few weeks apart. [120]
