WebFeb 2, 2024 · This shows Earth with the ISS in orbit. As the ISS is propagated, perturbations from the Moon, Sun, and all the planets are taken into account. But Earth is treated as a … The planet Earth has a rather slight equatorial bulge; its equatorial diameter is about 43 km (27 mi) greater than its polar diameter, with a difference of about 1⁄298 of the equatorial diameter. If Earth were scaled down to a globe with an equatorial diameter of 1 metre (3.3 ft), that difference would be only 3 mm (0.12 in). While too small to notice visually, that difference is still more than twice the largest deviations of the actual surface from the ellipsoid, including the tallest mountains and …

Web1 day ago · In this paper, the secular evolution of a test particle orbiting around an oblate central star with an eccentric exterior companion is studied. That is, two perturbing effects are included: the stellar oblateness and the tidal gravitational force from the outer companion. ... the planet's mass m should have m ≲ 10m Earth to disregard its ... Webthe oblate earth is less when perigee is near the equator. For long-lived satellites whose orbits are inclined to the equator at an angle not too near 63 40, perigee makes many revolutions about the earth and atmospheric oblateness gives rise to a periodic effect, whose period is equal to the interval
