# Is there a way to find the dates that a solar eclipse happens while Ceres is in alignment with Earth? [closed]

In the game i'm working on the Earth was hit by a Coronal Mass Ejection during a solar eclipse. I'm looking for dates between 2100 and 2300 where a base on Ceres would be protected by being in the shadow of the Earth.

The story requires the base on the far side of the moon and most space infrastructure being destroyed at the time.

• Most likely there is no such perfect alignment, eclipse or no eclipse; the orbit of Ceres has a different inclination than the orbit of the Earth, so that the little planet would need a very large dose of luck to find itself ever perfectly aligned with the Earth and the Sun. (And Ceres is really far away; Earth is much too small to offer significant protection from a coronal mass ejection.) (Especially given that the Moon itself could not protect Earth, and the Moon is so very much closer...) Commented Nov 9, 2022 at 21:17
• It's a videogame, of course the rule of cool has to be kept in mind and balanced against reality. Commented Nov 9, 2022 at 23:20
• (a) Why did someone downvote this question? +1 to counter that vote. (b) While John's answer is correct and the comments by Gault and AlexP are both valuable - who cares?! You're completely right about the "Rule of Cool." It's not impossible for Earth to shield Ceres, just so unlikely that it's not worth trying to calculate everything. Forget everything we've said and use the idea anyway. I like it.

While you have the hard-science tag on this question, the answer is "Earth cannot shield Ceres from a CME." Earth is not nearly large enough to do the job: if it ever transits the Sun as seen from Ceres, it will be a small black dot, smaller than we see Venus as when it transits the sun as seen from Earth.
