Wouldn’t it be troublesome if it rained or clouded and the stars were not seen for a long time?

What a night“Virtual Tour”Let’s go to.destinationProxima・ CentaurusProxima Centauri is known as the closest star to the Solar System. The word “Proxima” in Latin means “closest”. Despite its proximitythe centaurdirection,Around4.2light year distanceIt takes more than 4 years even at the speed of light.

In this video, when you leave the solar system (Earth)“essence”shining starsAlpha Centauri and Alpha CentauriYou can see it.Finally, when you get close to Alpha Centaurifaint red starpasses through. This star is Proxima Centauri. Proxima Centauri is a type of star called a “red dwarf”, and its size is11etc., can not be seen with the naked eye.

The closer you get to the Alpha Centauri,a“When”BYou can see that it was a double star (a binary star). In fact, Proxima Centauri is the “α Centauri system” or “Alpha Centauri system” in this system.cThe star in Centaurus is Alpha Centauri.“Tri-Double”So it was. This video ends when the sun is visible in the background.

The orbiting planet Proxima Centauri in 2016 (exoplanet)Proxima CentauriBhave found.

The following video is similar to the first video at first, but we will focus on the faint red star Proxima Centauri. The last stage is the exoplanet Proxima CentauriBDrop shadows for at the front and ends.

Proxima CentauriBteeth“habitable area”It is believed to orbit in the interior. The habitable zone refers to the planetary space in which life (terrestrial life) may specifically live.Liquid water may be on the surface of the planetmeans that there is.

In the last video, Proxima CentauriBButGreen colorDepicted as rotating in the habitable zone as shown in. The second half is Proxima Centauri which the artist imaginedBA surface (appearance) is also drawn, and the side watching the video is also fictional.

Recently, Proxima CentauriBAnother exoplanetProxima Centauricand Proxima Centauri.DrIt has also been reported.

I don’t know if there will ever come a day when a virtual tour to Proxima Centauri will become a real one, but Wings of Imagination can always fly “in the air” through space and time.
