This phenomenon is a rare sight, and it will be the last time seven planets can be seen simultaneously so well until 2040.

While four of the planets - Mercury, Venus, Jupiter, and Mars - will be visible to the naked eye, you will require a telescope to spot Saturn, Uranus and Neptune.

The best chance to spot as many planets as possible will be just after sunset on Wednesday, Thursday and Friday.

While it's not uncommon for a few planets to be on the same side of the Sun at the same time, it is rare for most, or even all of the planets to align like this.

A seven-planet alignment is, of course, the rarest of all.

According to Star Walk, a sky-gazing app, Tokyo got the first glimpse of the planetary parade first on February 22, followed by New York on February 25.

Worldwide, the best day to see the alignment will be February 28.

Dr Edward Bloomer, astronomer at the Royal Observatory Greenwich, has a few tips for your best chance at observing the planetary parade.

"Avoid looking at your phone, get comfortable, and ensure you have an unobstructed view of the horizon,” Bloomer said.
