Have you ever wondered if all the planets in our solar system will align one day? Astronomers say it’s not going to happen. But that doesn’t totally mean it’s never going to happen. According to scientists, the last time the seven celestial neighbors shared a night sky was in 949. However, this will happen again on May 6th of 2492 when Mars and Jupiter are visible near each other.

Since this has never happened before, we may see some people wondering about what could potentially occur during an alignment of all eight planetary bodies within a single small galaxy. 

However, astronomers have noted that there is no chance for it happening anytime soon because these events are rare and their timing can’t be predicted with any accuracy beforehand; they only take place when celestial mechanics allows them to do so at random points throughout time without any predictability or pattern whatsoever. 

One other thing that is really important is Planetary alignment. Planetary alignment is a perspective-dependent phenomenon. If three planets appear to be aligned from the earth’s point of view, they might not necessarily be in that same relative position as viewed by someone on the sun. This means it isn’t something fundamental about their geometry or proximity; rather, this effect comes down to our own vantage points and how we perceive them.

Despite what fictional and pseudo-science authors believe, planetary alignments have no significant effect on earth life. The gravitational pulls of the planets are so weak that they create negligible effects like changes in ocean tides or fluctuations in atmospheric pressure.

On May 6th, 2492 the eight planets will be closest to each other. However, they won’t all align and lie on a single line in space but instead form a 180-degree wide “band” of stars. ​​On September 8, 2040, the planets Jupiter, Saturn, and Mars will be in a line with Mercury. The five visible planets at night are an interesting sight to see for those who know what they’re looking for!


When did the last 3 planets align last?

The next three-planet conjunction won’t be for a while. The last time there was one, it happened in 2015 with Venus, Jupiter, and Mars all appearing near each other. Luckily for us, this isn’t the only planetary alignment happening soon! On February 19th, 2021 Earth will pass through the tail of Halley’s Comet making it visible to anyone on earth at night that week (weather permitting).

A planetary alignment is an arrangement of six or more planets in which they appear to form a straight line from the perspective of Earth. These alignments happen every one hundred years and are rare because it takes many thousands of years for all these celestial bodies to orbit around the sun together.

What will happen if the planets align?

The planets have no effect on our lives. The gravitational pull of the sun and moon is so weak that it has negligible effects on earth life, therefore aligning the planets won’t help us either.

What planet is close to Earth right now?

Did you know that the planet closest to Earth is Venus? To find out, subtract the smaller radius from the bigger one for each pair. The smallest distance gives us our closest neighbor: That’s Venus!
