The maximum size of a raindrop is typically around 5 millimeters in diameter. Raindrops larger than this size are rare because they become unstable and break apart due to air resistance as they fall through the atmosphere. However, under certain conditions such as in intense thunderstorms or tropical cyclones, raindrops can grow larger than 5 millimeters through a process called coalescence, where smaller droplets merge together to form larger ones. **

The speed at which a raindrop falls from the sky depends on its size and the air resistance it encounters. On average, a raindrop falls at a speed of about 8-9 meters per second (18-20 miles per hour). However, larger raindrops can fall faster due to their greater mass and gravitational pull, while smaller raindrops may fall more slowly due to air resistance. **
