Planets are in the same general region of the sky.
When astronomers use words like “planetary alignment”, they don’t mean a literal lining up. They just mean that some of the planets are in the same general region of the sky. And this type of “alignment” almost never happens to all the planets, but instead happens to two or three planets at one time. In reality, the planets do not all orbit perfectly in the same plane. Instead, they swing about on different orbits in three dimensional space. For this reason, they will never be perfectly aligned. It’s like waiting for a swarm of flies circling your head to all line up. The planets in our solar system never line up in one perfectly straight line like they show in the movies. If you look at a two-dimensional plot of the planets and their orbits on a piece of paper you may be lead to believe that all the planets will circle around to the same line eventually. In reality, the planets do not all orbit perfectly in the same plane. It is not going to happen. When astronomers use words like planetary alignment, they don't mean a literal lining up. They just mean that some of the planets are in the same general region of the sky. And this type of alignment almost never happens to all the planets, but instead happens to two or three planets at one time. The type of planetary alignment shown in this artistic rendering never happens Report Abuse. It means absolutely nothing. It's inevitable that planets and stars will align from time to time, but it has absolutely no effect on the Earth or its inhabitants. But such alignments are pretty to look at: take a look just after sunset of Jupiter and Venus in the southwestern sky.  · just now. Report Abuse. The planets only align in a very rough fashion. When astrologers speak of the planets being aligned (something which doesn't really concern astronomers) they don't mean that the planets will actually all lie on a straight line at some instant of time. Best Answer: Every once in a while some of the planets happen to line up. They might appear close together in the sky when this happens. Nothing bad ever happens on Earth as a result of planetary alignments. The planets are not going to align on Friday. They're actually all over the place, not aligned at all. The most interesting thing that will happen on Friday is that the winter solstice will occur (as happens every winter) Here, we have Earth. Mars, Jupiter, and so forth. So, alignment means that you can draw a straight line through the planets and the sun. So, therefore, we can draw a straight line between the middle of the sun and the planets. And, this is what we call when the planets are in alignment. The planets' alignment has to do with all eight planets orbiting the sun. Find out what the planets' alignment means with help from an experienced educator in this free video clip. Part of the Video Series: Astronomy Lessons. Here is a list of each planet (including Pluto and Chiron) showing which sign they are currently in, whether they are in a retrograde motion, and what will happen to them next. Mercury (retrograde) in Libra. Mercury goes Station Direct in Libra at.  It’s still not ALL of the planets, and we’ll live through that one too. These make very interesting sights in the night sky, but they don’t affect anything on Earth, except for causing useless anxiety in people who don’t understand astronomy. 1  #science. 2  #cwnl. 3  #astronomy. 4  #answer bag. 5  #space. Luckily, some very smart people have worked out the math behind planetary orbits and we can calculate where any planet will be on any date. You can do this, too, thanks to the internet. So let’s play! On May 5, 2000 there was a famous alignment of Mercury, Venus, Earth, Mars, Jupiter and Saturn in line with the Sun.
