Maybe the magnitude of the distance from Earth to Sun changes at a closer rate, but even this is nearly 180 MPH if I'm calculating correctly.

| − | ::'''ChatGPT:''' In the latest xkcd comic, two characters are discussing an elliptical orbit and the rate at which Earth is approaching the sun. One character, Ponytail, is suspicious when she sees a normal number (65 miles per hour) in their calculations and suggests that scales in astronomy should all be incomprehensible. This is a reference to the fact that astronomical numbers are often very large or very small, and can be difficult for non-astronomers to comprehend.

| − | Why is it as big as 65 mph? Where did the 65 mph figure have come from? A formula? Taking a linear change from minimum velocity (-500 m/s 12 weeks earlier), 4 days before the perihelion gives 86 km/h (53 mph), three days gives just 64 km/h (40 mph). But those are surely too big, since the rate of change of radial velocity would be slowest around perihelion and aphelion. I wouldn't expect the above-calculated rate of change until weeks out from perihelion. [[Special:Contributions/172.68.210.5|172.68.210.5]] 08:23, 6 December 2022 (UTC)
| |
| − | :Using an ephemeris service, I get 27.6 m/s or 61.8 mph- a bit lower than Randall's record but still in the ballpark. The reason is probably because of the effect of the Moon's orbit on Earth. Of course it's not a huge effect, but when we're working in just a few miles per hour, it definitely has a monthly effect.
| |
| − | :: I did a rough calculation using the position of the Earth-Moon barycentre, and came up with an average Sun-relative radial speed (unsigned velocity) for the Moon of 26 km/h (16 mph). So yes, that could explain some of it, but I still think the contribution of Earth's orbit would be very small around the perihelion (and aphelion).

| − | Just changed the "weight" of the Earth to the "mass", in the explanation. Apart from anything else, the weight of the Earth standing on a typical human('s feet?) is ''exactly equal'' to the weight of a typical human standing on the Earth. And things would be screwy, if not. And don't try to 'weigh' the Earth upon the surface of a duplicate Earth, that invokes a number of Health And Safety violations, at minimum, and the results would be questionable.

| − | I interpreted the title text not as the 12-solar-mass star bending the light from laser pointers, but the laser pointers *themselves* "following" the star because they're close enough to it to orbit said star (or at least, on hyperbolic trajectories influenced by the star).
