TOI-4487 A b: A Jupiter-Like Planet Orbiting a Hotter, Larger Star

TOI-4487 A is a star 1560 light-years away with one known planet, TOI-4487 A b. The star is 2.45 billion years old, has a mass of 1.38 solar masses, a radius of 1.63 solar radii, and a temperature of 6210 K. Its reported mass and radius estimates are larger than the Sun's, and its reported temperature is hotter than the Sun's.

TOI-4487 A b is a Jupiter-like planet discovered by transit in 2025. A transit occurs when a planet passes in front of its star from our viewpoint, causing a small dip in observed brightness. The planet completes an orbit every 3.95 days. Its radius is 14.6 Earth radii, larger than Earth's, and it exceeds four times Earth's radius.

TOI-4487 A b has a mass of 397 Earth masses, also larger than Earth's and roughly 1.25 times Jupiter's mass. Its mean density is 0.703 g/cm³, 0.128 times Earth's.
