  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 .

  3. ZTF J153932.16+502738.8 - Wikipedia

    en.wikipedia.org/wiki/ZTF_J153932.16+502738.8

    The orbital period is decreasing at 2.373 × 10 −11 seconds per second giving a characteristic timescale of 210,000 years. [1] This decay is mostly due to the emission of gravitational waves, however 7% of the decay could be due to tidal losses. [1] The decay is predicted to go for 130,000 years when the orbital period should reach 5 minutes.

  5. Orbiter (simulator) - Wikipedia

    en.wikipedia.org/wiki/Orbiter_(simulator)

    Orbiter was developed as a simulator, [14] with accurately modeled planetary motion, gravitation effects (including non-spherical gravity), free space, atmospheric flight and orbital decay. [15] [16] The position of the planets in the solar system is calculated by the VSOP87 solution, while the Earth-Moon system is simulated by the ELP2000 ...

    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. [24]

  8. Gravitational-wave astronomy - Wikipedia

    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.

    NFL players have sky-high salaries and contracts that would make the average person feel faint. They also get slapped with fines left and right, some frivolous and some substantial.
