If Jupiter changed the sun, would Europa still be the most suitable planet for immigrants?

First of all, if Jupiter becomes the sun, all the ice on Europa's surface will melt, and the whole planet will be a Wang Yang with no land at all.

Secondly, Europa's mass is too small to maintain its own atmosphere, and human beings can't survive without it.

Finally, Europa is influenced by Jupiter's gravity. Just as the moon is to the earth, Europa always faces Jupiter (tidal locking) in the same way. There is no day or night, spring, summer, autumn and winter.

To sum up, it is not suitable for immigration.
