The easiest exoplanets to detect — “hot Jupiters” — can be found in the sky even with an amateur telescope, Vladislava Ananyeva, a researcher in the Planetary Physics Department at the Space Research Institute (IKI) of the Russian Academy of Sciences, told Sputnik.

“To detect a hot Jupiter, it is enough to use a 10-centimeter amateur telescope and take photometric measurements at least once every 10 minutes. This allows you to create light curves and identify transits,” Ananyeva said.Hot Jupiters have masses ranging from 0.3 to 13 times that of Jupiter and orbit their stars in less than 10 days. They were the first exoplanets ever discovered. While not the most common type of planet outside the Solar System, their ease of detection has led to several hundred being known.The transit method does not allow direct observation of the planet itself, but it provides clear evidence of its presence through changes in the star’s brightness. When the planet passes in front of the star, the star appears slightly dimmer. By measuring the depth and duration of this dimming, astronomers can determine the planet’s size and orbital period.
