Some of the best studied exoplanets are the hot Jupiters: Jovian planets with mercurial orbits (P < 10 days). These strange planets have played an outsized role in exoplanetary science. This is not because they are common—only 1% of stars have one—but because they are so readily detectable with Doppler and transit techniques, and easy to characterize using other methods. However, since their discovery 17 years ago, hot Jupiters have posed a considerable challenge to our understanding of planet formation and orbital evolution. How did they move from their birthplaces beyond several AU to their current parking spots right next to their stars? I will present an observational overview of what we know about these high-profile yet mysterious planets. I will present the latest results of our spin-orbit measurements; a search for highly eccentric proto-hot-Jupiters in the Kepler field; a multi-wavelength search for their “cool friends”; and a reassessment of their relative occurrence rates from Doppler surveys and the Kepler Mission.
