tropic of Ophiuchus

[GrannyDeepSea]

I was told that Earth's 'tropic' points used to be Cancer and Capricorn and now they are Taurus and Sagittarius...but now that I've seen the Tropic of Ophiuchus on other planets in our solar system (in another post on this site), I'd like to know if Earth's 'tropic of Sagittarius' is actually a tropic of Ophiuchus, as well.
Thanks

Hi there, welcome to SDC.

The Earth's Tropic of Sagittarius is in Sagittarius, i.e the constellation the Sun is front of on the Northern Winter Solstice / Southern Summer Solstice on December 21st / 22nd.

Saturn & by default the major moons of Saturn too (Titan, Rhea, Dione, Enceladus, Mimas, Iapetus, etc) have the southern Tropic of Ophiuchus, northern Tropic of Taurus.

The asteroid 433 Eros has the southern Tropic of Corvus, (Northern Tropic of Pisces) a constellation not even on the ecliptic as viewed from Earth (though obviously it is on 433 Eros's ecliptic).

I will dig & see what else comes up.
