All seven planets are going to line up within the evening sky on Friday in a uncommon planetary parade that won’t be repeated for an additional 15 years.
The celestial show will see Mars, Jupiter, Uranus, Venus, Neptune, Mercury, and Saturn to seem on the identical time – climate allowing – between sundown and 6:30pm on 28 February.
That is anticipated to be the final time all seven planets will align in such a approach till 2040, so eager stargazers are suggested to set a reminder to catch the cosmic occasion.
We’ve spoken to knowledgeable astronomers who’ve damaged down the science behind this uncommon alignment and have shared some high suggestions that will help you take advantage of this magical planetary parade.
What’s a planetary parade?
“A planetary parade is a second when a number of planets are seen within the sky on the identical time,” says Dr Greg Brown, astronomer at Royal Observatory Greenwich. “How spectacular a parade it’s will depend upon what number of planets are in it and the way seen they’re.”
This week, all seven planets are technically seen within the sky without delay, although they aren’t all equally straightforward to identify.

“Mercury, Neptune and Saturn are all very near the horizon within the early night and, notably within the case of Neptune and Saturn, will wrestle to be seen within the twilight,” notes Brown. “As well as, Uranus, like Neptune, may be very faint, making it nearly unimaginable to search out and not using a pair of binoculars or a telescope.
“Venus, Jupiter and Mars, nevertheless, are all very straightforward to see with the unaided eye.”
How widespread is it?
“Teams of three, 4 and even 5 planets being seen aren’t unusual, commonly showing all through annually,” says Brown. “However, the extra planets are concerned, the extra issues must be aligned to be seen without delay. This makes full seven-planet parades pretty uncommon.”
Why does this occur?
“Planetary alignments happen as a result of the planets in our photo voltaic system orbit the Solar inside roughly the identical airplane, often known as the ecliptic airplane,” explains Dr Shyam Balaji, researcher in astroparticle physics and cosmology at King’s Faculty London. “As they orbit at totally different speeds and distances from the Solar, there are moments after they seem to line up from earth’s perspective.”
When would be the greatest time to identify it?

“The alignment is anticipated to be seen from February 23 to February 28, 2025,” says Balaji. “However the peak viewing alternative is on February 28, shortly after sundown, when the planets will likely be positioned above the western horizon.”
Will the climate have an effect on this?
“The evening will must be away from clouds throughout a lot of the sky to identify the entire planets,” says Brown. “When trying by means of a telescope or binoculars it can additionally assist if the evening continues to be, with little in the best way of wind, as that may make options on the planets just like the bands on Jupiter or the poles of Mars far simpler to identify.”
Happily, the most recent climate forecast from the UK Met Workplace exhibits near-perfect viewing situations for the planetary parade.

5 tricks to maximise your possibilities of seeing the celestial occasion
1. Discover a location away from metropolis lights
“The decrease the sunshine air pollution, the better it’s to see faint objects within the evening sky, so being out within the countryside will likely be a plus,” says Brown.
2. Think about using binoculars or a small telescope
“Discovering Mars, Jupiter and Venus will likely be no bother in any respect, seen to the unaided eye shortly after sundown, however discovering any of the opposite will possible require a pair of binoculars or a telescope,” highlights Brown.
3. Look forward to the solar to set
“When you do go searching for Saturn, Neptune or Mercury with a telescope or binoculars, look ahead to the solar to set to keep away from trying straight at it,” advises Brown. “However as soon as it has set, don’t dangle round, as all three disappear under the horizon very quickly after sundown.”
4. Use a smartphone adaptor
“Take into account a smartphone adaptor on your telescope that lets you take a picture of precisely what you’ll see along with your eye when trying into the eyepiece,” suggests Brown.
5. Search for moon shapes

“Utilizing a telescope, attempt searching for the moons of Jupiter or the form of the illuminated a part of Venus’s floor – like a tiny crescent moon,” recommends Brown.
When will the following planetary parade be?
The following prevalence of 5 or extra planets showing on the identical time will likely be 2028, whereas six planets will line up in 2034.
A planetary parade of seven planets will then happen in 2040.
