I imagine the day would be cut in half for anything living in the shadow. Is this object reflective? Since a portion of the object is in space, there would be a hot side and a cold side. I wonder if it would act as a giant heat sink dropping the temp in the local area?
The day’d be the same length, they’d just spend a lot of it in shadow. If there’s 35 miles of it sticking out of the ground, and it’s oriented east-west, how far north of the landing zone would you have to be to ever see the sun?
If it’s oriented north-south, it looks (from Google satellite maps) like it would block the prevailing winds, which would (for the short term) cause a huge pileup along the face of the ship, and eventually there’d be huge winds going around the ends of it, which probably wouldn’t be so much fun for the people living in that one tiny little town in the northeast…
That depends on the time of year. If it’s local summer, you’d always get at least a brief glimpse of the Sun near rising and setting. At the equinoces, you wouldn’t see the Sun at all right next to it, but would even just a little bit further out. Winter solstice is when the no-day zone would extend the furthest.
