Dr Shyam Balaji, researcher in astroparticle physics and cosmology at King’s College London, said: “The best time to observe the planetary parade is on 21 January, just after sunset. While the alignment will be visible for several weeks, another notable alignment will occur on 28 February.
“On 21 January, six planets will align: Mars, Jupiter, Uranus, Neptune, Venus, and Saturn.
On 28 February a seven-planet alignment will occur, including Mercury along with the six planets mentioned above.”
