The exoplanet PSR J2322-2650b is shaped like a lemon because it orbits a normal star.
Why it is true
The exoplanet PSR J2322-2650b, with a mass similar to Jupiter s, orbits a pulsar at an extremely short distance, completing an orbit in just 7.8 hours. The intense gravity of the pulsar deforms the planet, giving it an elongated shape resembling a lemon.
