Geometric properties of $N$ random points distributed independently anduniformly on the unit sphere $\mathbb{S}^{d}\subset\mathbb{R}^{d+1}$ withrespect to surface area measure are obtained and several related conjecturesare posed. In particular, we derive asymptotics (as $N \to \infty$) for theexpected moments of the radii of spherical caps associated with the facets ofthe convex hull of $N$ random points on $\mathbb{S}^{d}$. We provideconjectures for the asymptotic distribution of the scaled radii of thesespherical caps and the expected value of the largest of these radii (thecovering radius). Numerical evidence is included to support these conjectures.Furthermore, utilizing the extreme law for pairwise angles of Cai et al., wederive precise asymptotics for the expected separation of random points on$\mathbb{S}^{d}$.
