Message: <blockquote data-quote="Glade Riven" data-source="post: 5411953" data-attributes="member: 86468">RE: Previous Thread:An interesting read...and still working my way through it. I was thinking about having seasons through the power of an eliptical orbit, but may be an extra complication that I don't want to deal with. It is techtonically active, partially from the strain of tidal forces...maybe the core still rotates while the surface is tidally lock. That could make for some interesting (and cataclysmic) plate tectonics. RE: Aexalon:Well, orbits of Hot Jupiters have been noted at distances of .1 AU (14.9 million km), and the solar mass of this particular sun needs to be less than 1.25 of our own for a stable orbit that close to the star. Now, my math is going to get a little fuzzy here, but with a few basic ratios and a thrown together model in 3DSMax, a sun of our size and a planet like <a href="http://en.wikipedia.org/wiki/Kepler-7b" target="_blank">Kepler-7b</a> would be visible from the Earth passing between us and the sun. The Chinese report sunspots as early as 300+ BC. So while it's not the full eclipse (such as when the moon passes between us and the sun), it would work as a basis for the development of measuring time (for the light side). Or, y'know...fantasy ad hoc the whole thing <img src="https://cdn.jsdelivr.net/joypixels/assets/8.0/png/unicode/64/1f600.png" class="smilie smilie--emoji" loading="lazy" width="64" height="64" alt=":D" title="Big grin    :D"  data-smilie="8"data-shortname=":D" />. Really, though, the whole thing was a reason to add the concept of a "day" to a planet without a day/night cycle, so it doesn't have to be like a typical solar eclipse. Addendum: Actually, a Kepler-7b like object crossing between Phaetos and it's sun (assuming an Earth size planet and same size sun) should be quite noticible in the permanent dusk/dawn - since one could look at the sun without burning out one's retinas. It won't dim anything overall, but the black spot transversing it would be noticible.</blockquote>
