celestial sphere for the observer, while there can be a huge distance between the planets. However, visually from Earth, one would think that the two objects are practically merging.

In fact, two space objects will be each otherfrom each other at a distance of about 750 million km. Viewers will be able to see them in the sky even with the naked eye - they will look like a bright and noticeable double star. The Earth is located at a distance of 890 million km from Jupiter.

In space there are highways for fast travel. How will flights change?

This is a unique event, because previously this happened in 1226, then there was a slightly greater distance between the planets. The next time such a rapprochement will occur is only on March 15, 2080.

The brightness of Jupiter at this moment will be 1.9 stellarmagnitude, and Saturn - 0.8. It is best to observe the phenomenon through special devices - binoculars or a telescope. In addition, viewers will be able to see the moons of Jupiter or even the rings of Saturn.
