The first exoplanet for which transits were observed for HD 209458 b, which was discovered using radial velocity technique. These transits were observed in 1999 by two teams led David Charbonneau and Gregory W. Henry. [19] [20] [21] The first exoplanet to be discovered with the transit method was OGLE-TR-56b in 2002 by the OGLE project. [22 ...
Lens alignment. The ASTERIA concept was a follow-on to the proposed 3U CubeSat mission called ExoplanetSat that was designed in the early 2010s. [4] [8] The ASTERIA telescope is a 6U CubeSat measuring 10 × 20 × 30 cm, and has a mass of 12 kg (26 lb). [1] [7] Power was supplied by deployable fixed solar panels and rechargeable batteries. [5]
Origins and Composition of the Exoplanet Analog Uranus System: 2030 Atlas V 511 or SLS: NASA: Orbiter In progress Proposed to investigate the structure of Uranus's magnetosphere and interior, enabling detailed studies not achievable with a flyby mission.

Transit-timing variation is a method for detecting exoplanets by observing variations in the timing of a transit. This provides an extremely sensitive method capable of detecting additional planets in the system with masses potentially as small as that of Earth. In tightly packed planetary systems, the gravitational pull of the planets among ...
Because the word 'inclination' is used in exoplanet studies for this line-of-sight inclination then the angle between the planet's orbit and the star's rotation must use a different word and is termed the spin–orbit angle or spin–orbit alignment. In most cases the orientation of the star's rotational axis is unknown.
The HARPS can attain a precision of 0.97 m/s (3.5 km/h), [2] making it one of only two instruments worldwide with such accuracy. [citation needed] This is due to a design in which the target star and a reference spectrum from a thorium lamp are observed simultaneously using two identical optic fibre feeds, and to careful attention to mechanical stability: the instrument sits in a vacuum vessel ...
WASP or Wide Angle Search for Planets is an international consortium of several academic organisations performing an ultra-wide angle search for exoplanets using transit photometry. The array of robotic telescopes aims to survey the entire sky, simultaneously monitoring many thousands of stars at an apparent visual magnitude from about 7 to 13.
Spectro-Polarimetric High-contrast Exoplanet REsearch (VLT-SPHERE) is an adaptive optics system and coronagraphic facility at the Very Large Telescope (VLT). [1] It provides direct imaging as well as spectroscopic and polarimetric characterization of exoplanet systems.
