Such an event is commonly known as a "planet parade," though NASA noted that the moniker is not a technical astronomical term. Planet parades are how astronomers and stargazers refer to the events ...

The four-planet lineup that began in January concludes by mid- to late February, as Saturn sinks increasingly lower in the sky each night after sunset, according to NASA. While Mercury will briefly join Saturn later in February in the post-sunset glow, both planets will be too low and faint for most observers to spot.

Look up this week for February’s full snow moon and to catch the last glimpse of a visible parade of planets in the night sky before they fade from view.
