Asteroid sizes determined with thermophysical model and stellar occultations
Context. The sizes of many asteroids, especially slowly rotating, low-amplitude targets, remain poorly constrained due to selection effects. These biases limit the availability of high-quality data, l...

Bislang sind primordiale Schwarze Löcher nur theoretisch beschrieben und es ist unklar, ob sie wirklich existieren. Die Forscher schlagen vor, in sehr alten Felsen, altem Glas oder festen Strukturen in sehr alten Gebäuden nach solchen Tunneln zu suchen. 🔍

#Comet (Centaur) *29P/Schwassmann-
Wachmann 1* orbits the Sun between Jupiter and Saturn at around 6 au (~900 million km, see below). A new paper by Pereira et al. has now constrained its orbit to an accuracy of 260 km! Isn't that incredible?

The orbits of Mercury, Venus, Earth, Mars, Jupiter and Saturn are shown in addition to the one of comet 29P. This comet orbits close to Jupiter and has a slightly inclined orbit.
