Astronomy divided by general technique used for astronomical research:
Astrometry – study of the position of objects in the sky and their changes of position. Defines the system of coordinates used and the
kinematics of objects in our Galaxy.
Observational astronomy – practice of observing celestial objects by using telescopes and other astronomical apparatus. It is concerned with recording data. The subdisciplines of
observational astronomy are generally made by the specifications of the detectors:
Hot Jupiter – an exoplanet whose characteristics are similar to Jupiter, but that have high surface temperatures because they orbit very close to their parent stars, whereas Jupiter orbits its parent star (the
Sun) at 5.2 AU (780×106 km), causing low surface temperatures.
Hot Neptune – an exoplanet in an orbit close to its star (normally less than one astronomical unit away), with a mass similar to that of Uranus or Neptune.
Pulsar planet – a planet that orbits a pulsar or a rapidly rotating neutron star.
Rogue planet (also known as an interstellar planet) – a planetary-mass object that orbits the galaxy directly.
