Earth changes?

The phrase “earth changes” is often used to refer to some kind of disastrous event that will adversely affect much if not most life on Earth, including human life. There is thought about preparing ourselves for it, but the phrase is vague about what it could be.

It differs in severity from coronal mass ejections like the Carrington event of 1859, Those CMEs, but do not in general threaten life rather than power grids, which could be devastating enough in this modern age of dependence on electronic devices of all kinds. There are calls such as the Shield Act to harden electric grids against them.

Grazing planemos

There are interstellar objects that might make a grazing contact with the sun, We recently had one such object, Oumuamua, an odd-shaped body about ten times longer than it was wide, with other strange attributes. The general name for interstellar planets, not bound to a particular star, is planemo. Most of them are expected to be round. They could be as large as planets. The term generally applies to a rocky object, likely with a hot core, that could wander among the stars, and could provide a site for an outpost for star travelers, if the core is hot enough to geothermally support such an outpost.
