Five planets will align that will be visible from Earth in June. For the first time since December 2004, Mercury, Venus, Mars, Jupiter, and Saturn are aligning — in that sequence.
According to Sky & Telescope, while seeing three planets close together is frequent, seeing five is unusual.
The planets are lined up in their normal order from the Sun, which is equally unusual, according to the American Astronomical Society's science magazine.
The five "naked-eye" planets became visible on June 3 and 4, but they will be significantly easier to view on June 24.
The line-up was visible with binoculars on the mornings of June 3 and 4, but only for about half an hour before Mercury was lost in the glare of the Sun.
However, on June 24, viewing will be at its best. Even when the distance between Mercury and Saturn grows larger, it becomes easier to see Mercury, making it simpler to observe all five planets.
The planets should be visible on the days leading up to this, even if it is cloudy. The optimum time to observe the line up on June 24 is 45 minutes before sunrise on the eastern horizon
