The Parker Solar Probe will zoom by the sun on Tuesday during a record-breaking flyby, coming within 3.8 million miles (6.1 million kilometers) of the solar surface during humanity's closest approach to a star. The uncrewed spacecraft will fly at 430,000 miles per hour (692,000 kilometers per hour), which is fast enough to reach Tokyo from Washington, DC, in under a minute, according to NASA. The speedy flyby will make the probe the fastest human-made object in history, the agency shared December 16 during a NASA Science Live presentation on YouTube.
