Musical Planets?

This artist's impression shows the view from the planet in the TOI-178 system found orbiting ... [+] furthest from the star.

The stars system—known as TOI-178, and about 200 light-years from us—features six planets, five of which are locked in a highly unexpected "rhythmic dance" as they move in their orbits.

In the video the rhythmic movement of the planets around the central star is represented through a musical harmony, created by attributing a note in the pentatonic scale to each of the planets in the resonance chain.

Quite a lot has been going on:

Rare three-planet conjunction of Mercury, Jupiter and Saturn to illuminate the

"From Friday evening to Monday evening, the planet Mercury will appear to pass first by Saturn and then by Jupiter as it shifts away from the horizon, visible each evening low in the west-southwest and setting before evening twilight ends,"  NASA said.

Planetary trios are relatively rare, although nowhere near as special as the recent great conjunction. Mercury, Venus and Jupiter will meet in the sky on February 13.

After that, another triple conjunction won't occur until April 2026, when Mercury, Mars and Saturn meet, according to EarthSky.

Astronomers discover six planets locked in an rhythmic motion as they orbit their central star  |

A puzzling line up of six-exoplanets moving in a rhythmic dance as they orbit their star have been discovered in a system 200 light years from Earth.

Researchers used the European Space Agency CHEOPS space telescope to detect the unusual explanatory formation - and it could shed light on how systems form.

University of St Andrews astronomers found five of the six planets are locked in a harmonic rhythm, where their orbits align in a consistent pattern to one another - which the team says suggests no major collisions when the system first formed.

Rocky planet discovered orbiting ancient star | West Hawaii Today

An illustration showing the structural components of the Milky Way galaxy. The star TOI-561 is located in the thick disc (marked in red-orange), which contains a rare, older population of stars. While nearly all known planets are found within the thin disc (marked in orange), the newly discovered rock-and-lava exoplanet orbiting TOI-561 is one of the first confirmed rocky planets orbiting a galactic thick disc star.
