Astronomers have mapped out the structure of supergiant star Antares: study

The video discusses Antares, the brightest star in Scorpius, highlighting its immense size and unique atmospheric properties. If placed in our solar system, Antares would envelop planets from Mercury to Mars, and its atmosphere would nearly reach Saturn. The star's wind acceleration zone is comparable to the distance from the sun to Uranus.

What is the wind acceleration zone of Antares and how does it compare to the distance between the sun and Uranus?

Explain the implications of Antares' size and atmosphere on its solar wind particles.
