  2. Orbital decay - Wikipedia

    en.wikipedia.org/wiki/Orbital_decay

    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 .

    en.wikipedia.org/wiki/Gravitational-wave_astronomy

    The first indirect evidence for the existence of gravitational waves came in 1974 from the observed orbital decay of the Hulse–Taylor binary pulsar, which matched the decay predicted by general relativity as energy is lost to gravitational radiation.

  5. Simplified perturbations models - Wikipedia

    en.wikipedia.org/wiki/Simplified_perturbations...

    Simplified Deep Space Perturbations (SDP) models apply to objects with an orbital period greater than 225 minutes, which corresponds to an altitude of 5,877.5 km, assuming a circular orbit. [ 3 ] The SGP4 and SDP4 models were published along with sample code in FORTRAN IV in 1988 with refinements over the original model to handle the larger ...

    [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 minimum orbital altitude is determined by the estimated time it would take for the fission products to decay to the radioactivity level present at launch. In the case of the DRACO reactor, that is about 300 years, which requires an orbit above about 700 km if the orbital decay time is to exceed that value.

    A reboost is the process of boosting the altitude of an artificial satellite in Low Earth Orbit [1] [2] [3] in order to delay its atmospheric re-entry due to orbital decay. [ 3 ] See also
