百科：TOI-5624 b
中文维基百科没有这个条目，下面是英文维基百科的原文。
TOI-5624 b is the innermost and smallest exoplanet discovered in the TOI-5624 system, located approximately 331 light-years from Earth in the constellation Ursa Major. The planet was confirmed in late April 2026 using the transit method.
Characteristics
Physical characteristics
The object is classified as a dense hot sub-Neptune, with a mass of 9.4±1.4 M🜨 and a radius of 2.314±0.035 R🜨. These parameters were determined using the radial velocity method and the European CHEOPS telescope. Its average density, equal to 4.00+0.60 −0.59 g/cm³, indicates the presence of a significant solid core surrounded by a less massive gaseous envelope.
Orbit
The planet is the closest to its host star, and therefore its orbital period is 3.3903473±0.0000054 Earth days, at a distance of 0.04201+0.00041 −0.00043 AU. Due to its proximity to the star, the equilibrium temperature reaches 1136 K or 863 °C.

TOI-5624 c is the second closest of the discovered exoplanets orbiting the star TOI-5624, located approximately 331 light-years from Earth in the constellation Ursa Major. The planet was confirmed in April 2026 using the transit method.
Characteristics
Physical characteristics
The planet is classified as a sub-Neptune, with a mass of 4.8±1.9 M🜨 determined by the radial velocity method, and a radius of 2.474±0.042 R🜨 determined by the CHEOPS telescope, with an uncertainty of less than 1.7%. The object's average density is 1.72+0.70 −0.69 g/cm³. Such a low value indicates a higher proportion of volatiles or a hydrogen-helium mixture in its composition.
Orbit
The orbital period around its host star is approximately 7.885385±0.000018 Earth days. The semi-major axis of the orbit is estimated to be 0.07374+0.00072 −0.00075 AU. The equilibrium temperature is approximately 858 K, or 584 °C.

百科：TOI-5624 d

TOI-5624 d is the third and largest discovered exoplanet orbiting the star TOI-5624, with a size approximately three and a half times the diameter of Earth. The planet was confirmed in late April 2026 using the transit method.
Characteristics
Physical characteristics
This planet is a puffy sub-Neptune. Its mass equals 4.9±2.2 M🜨, and its radius is 3.584+0.051 −0.050 R🜨. This makes it the largest in radius among the four transiting bodies in the system. The average density is extremely low, about 0.59+0.27 −0.26 g/cm³, which is comparable to the density of Saturn. This suggests the presence of an extended and massive atmosphere, constituting a significant part of the planet's volume. Consequently, the planet has a high transmission signal, making it a priority target for atmospheric studies using the James Webb Space Telescope.
Orbit
The planet's orbital period is 13.731468+0.000042 −0.000041 Earth days at an average distance from its parent star of 0.1067+0.0010 −0.0011 AU . The equilibrium temperature is estimated at 712.6 K, or 439.45 °C.
