HD 135344 A and Its Jupiter-like Planet

HD 135344 A is a star 462 light-years away with the spectral type A0 V, making it an A-type main-sequence star. Its mass is 2.32 solar masses, its radius is 1.56 solar radii, and its temperature is 9150 K. One planet is known to orbit this host.

That planet is HD 135344 A b, discovered in 2025 by imaging and classified as Jupiter-like, a size class for planets whose radius exceeds four times Earth's. Its mass is 3180 Earth masses, roughly 10 times Jupiter’s mass and larger than Earth’s, and its radius is 16.3 Earth radii, larger than Earth’s. Its mean density is 4.08 g/cm³, 0.74 times Earth's. No orbital period is reported for HD 135344 A b.
