The pull of the Sun's gravity caused it to speed up until it reached its maximum speed of 87.71 km/s (315,800 km/h; 196,200 mph) as it passed south of the ecliptic on 6 September, where the Sun's gravity bent its orbit in a sharp turn northward at its closest approach (perihelion) on 9 September at a distance of 0.255 AU (38,100,000 km ...
The maximum extent of the region in which the Sun's gravitational field is dominant, the Hill sphere, may extend to 230,000 astronomical units (3.6 light-years) as calculated in the 1960s. [3] But any comet currently more than about 150,000 AU (2 ly) from the Sun can be considered lost to the interstellar medium.
Until the discovery of 'Oumuamua, the fact that no comet with a speed greater than the Sun's escape velocity [30] had been observed was used to place upper limits to their density in interstellar space. A paper by Torbett indicated that the density was no more than 10 13 (10 trillion) comets per cubic parsec. [31]
Nasa is flying the fastest human-made object ever made closer to the Sun than anything has ever been ... Parker planned to get more than seven times closer to the sun than previous spacecraft ...
Putting the Sun immobile at the origin, when the Earth is moving in an orbit of radius R with velocity v presuming that the gravitational influence moves with velocity c, moves the Sun's true position ahead of its optical position, by an amount equal to vR/c, which is the travel time of gravity from the sun to the Earth times the relative ...

One passenger plane, a Virgin Atlantic flight traveling from Washington to London was pushed to nearly 1300kph (800mph), faster than the speed of sound, according to the US National Weather Service.
