A numerical N–body integration of the asteroid (4660) Nereus over 3.5 Myr shows the presence of the Kozai resonance and two secular resonances inside a horseshoe orbit with Venus.

The most highly evolved of today’s bars may become lenses over a Hubble time. Most galaxies in the early Universe are extremely clumpy, with ∼ 10 −10 M⊙ blue clumps that resembl...
