Seven planets will seem to align within the evening sky on the final day of February in what is called a planetary parade.
These planetary hangouts occur when a number of planets seem to line up within the evening sky directly.
“A planetary parade is a second when a number of planets are seen within the sky on the similar time,” stated Dr Greg Brown, an astronomer on the Royal Observatory Greenwich, instructed PA Media. “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 directly, although they aren’t all equally straightforward to identify.
“Mercury, Neptune and Saturn are all very near the horizon within the early night and, significantly within the case of Neptune and Saturn, will battle to be seen within the twilight,” Brown stated. “As well as, Uranus, like Neptune, may be very faint, making it virtually not possible to search out and not using a pair of binoculars or a telescope.
“Venus, Jupiter and Mars, nonetheless, are all very straightforward to see with the unaided eye.”
A parade of 4 or 5 planets seen to the bare eye occurs each few years, in line with Nasa.
“Teams of three, 4 and even 5 planets being seen aren’t unusual, often showing all through annually,” Brown stated. “However the extra planets are concerned, the extra issues have to be aligned to be seen directly. This makes full seven-planet parades pretty uncommon.”
An identical parade occurred final June, however solely two planets may very well be seen with none particular tools. Six planets have been seen in January – 4 to the bare eye – and now a dim Mercury joins the gang.
This month, Venus, Mars and Jupiter are seen to the bare eye. A faint Saturn and Mercury are near the horizon, making them laborious to identify. Uranus and Neptune may be glimpsed with binoculars and telescopes.
“Planetary alignments happen as a result of the planets in our photo voltaic system orbit the Solar inside roughly the identical aircraft, often known as the ecliptic aircraft,” Dr Shyam Balaji, a researcher in astroparticle physics and cosmology at King’s Faculty London, stated. “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.”
Balaji stated the perfect time to see the alignment within the UK was 28 February, “shortly after sundown, when the planets might be positioned above the western horizon”. The identical is true in Australia, the place stargazers ought to look north after sundown, and the US, with specialists suggesting these hoping to see the celestial present ought to head out about half-hour after sundown and keep away from vibrant lights.
Stargazing apps may help folks discover out the place to look simply after sundown all over the world.
To seek out the planets with a telescope, search for moon shapes, Brown stated. “Utilizing a telescope, strive in search of the moons of Jupiter or the form of the illuminated a part of Venus’s floor – like a tiny crescent moon.”
The planets will slowly make their exit by means of the spring.
