Five planets; Mercury, Venus, Mars, Jupiter and Saturn also appear in their proper order from the Sun.
This phenomenon is reportedly happening for the first time in a decade, and the formation will be visible during the early morning hours, just before dawn.
A spectacular sky show is taking place that hasn't been seen in almost two decades, and won't be seen again until 2040.
The best part is that no fancy telescopes are needed, as the naked eye can easily see the phenomenon of five planets aligning in the night sky.
American Astronomical Society's science publication notes that the planets are in their natural order from the Sun.
The five so-called "naked-eye" planets were visible beginning on June 3 and 4, but on June 24, they will be even easier to see.
On the mornings of June 3 and 4, the line-up was visible with binoculars — but only for about half an hour, before Mercury was lost in the glare of the Sun.
