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 position of Antares in the constellation of Scorpius when viewed from Earth?

• A star not visible from Earth

• The brightest star

• The second brightest star

• The dimmest star

If Antares were placed in our solar system, which planets would it envelop?

• From Mercury to Saturn

• Only Mercury

• From Mercury to Mars

• From Mercury to Jupiter

How does the length of Antares' atmosphere compare to its radius?

• It is half the radius

• It is equal to the radius

• It is 2.5 times the radius

• It is 5 times the radius

To which planet does Antares' atmosphere almost reach?

• Jupiter

• Uranus

• Saturn

• Neptune

What is the distance of Antares' wind acceleration zone compared to the solar system?

• Equal to the distance from the sun to Uranus
