In outer space, a human being can survive for approximately 15 seconds without protective gear. This is because the lack of atmospheric pressure and oxygen in space causes rapid decompression and asphyxiation. Additionally, the extreme temperatures and radiation in space can also be fatal. Therefore, it is crucial for astronauts to wear specialized suits that provide them with oxygen, temperature regulation, and protection from the harsh environment of outer space.

Outer space is located approximately 73 miles (118 kilometers) above Earth's surface. This is the distance at which the Earth's atmosphere becomes too thin for conventional aircraft to operate and where the conditions are more suitable for space exploration. At this height, astronauts and satellites can orbit the Earth and experience the microgravity environment of space.
