Orbital decay is a gradual decrease of the distance between two orbiting bodies at their closest approach (the periapsis) over many orbital periods. These orbiting bodies can be a planet and its satellite , a star and any object orbiting it, or components of any binary system .
2.10 ± 0.2: 6,500 ± 1,300: D: Precision pulse timing measurements of relativistic orbital decay. [14] PSR J0740+6620: 2.08 ± 0.07: 4,600: D: Range and shape parameter of Shapiro delay. Most massive neutron star with a well-constrained mass. [15] [16] [17] PSR J0348+0432: 2.01 ± 0.04: 2,100: D: Spectroscopic observation and orbital decay due ...
[2] [10] [11] [12] The ratio of observed to predicted rate of orbital decay is calculated to be 0.997 ± 0.002. [12] The total power of the gravitational waves emitted by this system presently is calculated to be 7.35 × 10 24 watts. For comparison, this is 1.9% of the power radiated in light by the Sun.
The planet's orbital period appears to be decreasing at a rate of 7.33 ± 0.71 milliseconds per year, suggesting that its orbit is decaying, with a decay timescale of 15.77 ± 1.57 million years. The anomalously high rate of orbital decay of WASP-4b is poorly understood as of 2021.

For a nuclide (A, Z) with a number of nucleons A and atomic number Z, double electron capture is only possible if the mass of the nuclide (A, Z−2) is lower. In this mode of decay, two of the orbital electrons are captured via the weak interaction by two protons in the nucleus, forming two neutrons (Two neutrinos are emitted in
