After hearing the new intelligence about Green Star,
Lu Chen fell into new hesitation.
Because, indeed, it was a problem that warranted serious consideration.
Assuming that Earth never stopped and continued wandering in the universe, then indeed, the sudden drop in the planet's surface temperature might result in a pale blue, almost white, color.
However, if Earth was already revolving within a Constant Star System,
then under the irradiation of constant starlight, the planet surface could indeed appear to be a deep blue.
Since both planets could potentially be Earth or neither, Lu Chen further inquired about the appearance of biological life on these two planets.
He wanted to directly determine from the life forms whether it was really Earth.
Unfortunately, at that time, Green Star did not particularly care, so no effort was spent on observing.
