[7] [9] It is the fastest object ever built on Earth. [10] The project was announced in the fiscal 2009 budget year. Johns Hopkins University Applied Physics Laboratory designed and built the spacecraft, [11] which was launched on 12 August 2018. [2]

The speedy flyby would make the probe the fastest human-made object in history, the agency shared December 16 during a NASA Science Live presentation on YouTube.
Pioneer 10 – launched in 1972, flew past Jupiter in 1973 and is heading in the direction of Aldebaran (65 light years away) in the constellation of Taurus.Contact was lost in January 2003, and it is estimated to have passed 134 astronomical units (AU; one AU is roughly the average distance between Earth and the Sun: 150 million kilometers (93 million miles)).
PSR J1748−2446ad is the fastest-spinning pulsar known, at 716 Hz (times per second), [2] or 42,960 revolutions per minute.This pulsar was discovered by Jason W. T. Hessels of McGill University on November 10, 2004, and confirmed on January 8, 2005.
To give you a glimpse of how amazing this connection can be, here's a list of man-made objects that fit the bill. #1 Bird Safe Glass Every day, hundreds of birds die from flying into glass windows.
The speed of gravitational waves in the general theory of relativity is equal to the speed of light in vacuum, c. [3] Within the theory of special relativity, the constant c is not only about light; instead it is the highest possible speed for any interaction in nature.
