... However, the word dwarf is not used because in normal usage it denotes size alone, not size in combination with distance from a star. In astronomy in particular, dwarf is used to indicate the opposite of giant. But minor is both broader in meaning, and already well-established in use more or less fo ...

As certain planets moved eastward across the sky, from one constellation to the next, over time they would periodically travel in small circles. This phenomenon was difficult to explain using the current geocentric model. The following i ...

... further away than Pluto. One can wonder whether its semimajor orbital axis fits in a generalized Titius-Bode law, in the same way as Pluto does. We performed a new least squares fit to a generalized Titius-Bode law including Eris and found that not only does Eris fit in the trend, but also that the ...

From planetesimals to planetary systems: a hardles race

Drag is computed from nodes around the particle and back reaction acts on the nodes. What is the effect ...
