Key Information
Solar Wind
| Type | Star |
| Diameter | 865,372 miles |
| Temperature | 9,900 °F |
| Star Type | G2V – Yellow dwarf |
| Date of Discovery | Unknown |
| Temperature (Corona) | Around 1,800,000 °F at its peak |
| Distance of Heliopause | At least 7,767,139,903 miles |
Learning Point
- The Sun emits particles from its surface creating what we call the Solar Wind. This constant flow of particles acts similar to wind on Earth and pushes out from the Sun, shaping atmospheres and the extent of our Solar System.
Project
- Identify how far the Solar Wind extends from the Sun.
- Overview
- Bow Shock
Location
| Located in | Solar System, Milky Way |
Fun Facts
- Richard C. Carrington first suggested that particles flowed out from the Sun after observing the first observations of a solar flare in 1859.
- Eugene Parker was the first person to form a complete theory of what we now know to be the solar wind in 1958.
- It was a Soviet spacecraft, Luna 1, that first observed and measured the solar wind in 1959.
- Voyager 1 was the first human object to pass the heliopause, the point when the solar wind stops.
