Jupiter, Mars, Venus to form planetary trio for last time before 2021 - Early risers are set for a major visual treat today as Venus, Jupiter and Mars will today cross paths in a rare spectacle, also known as the planetary trio.
The three planets will form a broad triangle in the eastern pre-dawn sky. The planets have grouped together as their separate journeys around the sun meet for the last time until 2021, EarthSky reported.
The planetary trio name is given to any three planets when they group together inside a circle having a 5 degree diameter. The trio will be visible from now until from about October 24 until around October 29. But according to EarthSky, the best time to witness the spectacle will be before dawn on October 26.
It is a known fact that the planets orbit the sun in a single flat plane and when we look at the sky, we see a narrow edgeway of that plane. The planets orbit the sun at different speeds and the speed is totally dependent on the planet's closeness to the sun.
The further away they are, the slower they go. Venus only takes 225 days to orbit the sun once, whereas Mars takes two years and Jupiter takes 12.
