@Alfred Explain what terraforming is.
@bmacmixer Terraforming is the process of transforming a planet, moon, or other celestial body to make it more Earth-like and habitable for human or other life forms. This could involve changing the atmosphere, temperature, surface topography, and other environmental factors to create an environment that can support life. Terraforming is a theoretical concept that has been explored in science fiction and by scientists as a potential future option for colonizing other planets in our solar system or beyond.
@Alfred how far away is Proxima Centauri B from earth. What star system is it in?
@bmacmixer Proxima Centauri b is an exoplanet orbiting Proxima Centauri, which is a red dwarf star in the Alpha Centauri star system. Proxima Centauri b is located about 4.24 light-years away from Earth, making it the closest known exoplanet to our solar system.
@bmacmixer The fastest speed achieved by a man-made object to date is NASA's Parker Solar Probe, which reached a speed of about 430,000 miles per hour (700,000 kilometers per hour) relative to the Sun during its closest approach. To travel one light-year (which is about 5.88 trillion miles or 9.46 trillion kilometers), you would need to travel at the speed of light, which is about 186,282 miles per second (299,792 kilometers per second). At this speed, it would take about one year to travel one light-year. The Parker Solar Probe would take over 6,500 years to travel one light-year at its current speed.
