PLATO and CHEOPS are two European Space Agency missions aimed at characterising exoplanets. CHEOPS is an S-class mission (small mission in ESA’s science program) which aims to characterise exoplanets already known to be orbiting around nearby bright stars. CHEOPS will target Earth- to Neptune-sized planets. PLATO is an M-class mission (medium size mission) aimed at finding  terrestrial exoplanets in orbits out to the habitable zone (HZ) of solar-type stars …

TESS will also utilise the transit technique to focus on targeting bright host stars, to look for Earth-sized planets. It is thus not surprising when people end up thinking: why launch two space-based exoplanet spacecraft to look for Earth-sized planets? The Transiting Exoplanet Survey Satellite (TESS) launched …

Here I will go through the steps I use when deciding on which exoplanet to observe using an amateur telescope. Step 1: Find objects which are bright enough. Go to the exoplanets.org/table and from the drop down menu on the upper left choose transit planets. Then press the big plus button (+) on the right and choose V mag under stellar params. You can move this table header next to …
