Is the exoplanet gj121 4b in the constellation Ophiuchus like the planet of Doctor who?

well its a show so im pretty sure it doesn't have any real world quality's....Is the exoplanet gj121 4b in the constellation Ophiuchus like the planet of Doctor who?Gallifrey isn't in Ophiuchus. It's not even in our galaxy. The series is fairly clear that Gallifrey's constellation is "Kasterborous".Is the exoplanet gj121 4b in the constellation Ophiuchus like the planet of Doctor who?There is no planet "gj121 4b" as an exo-planet is classified only by a letter (no number) so if there were a star called gj121 and it had an exo-planet it ould be called gj121 b
