Proxima Centauri b (Exoplanet Orbital In The Habitable Zone)

  • May 09, 2019

Today we have to talk about the star named Proxima Centauri B. This star is also called Alpha Centauri C.b. Proxima Centauri b is the exoplanet orbital in the habitable zone of the red dwarf star Proxima Centauri, which is the closest star of the Sun and the triple star system so let's get information about Proxima Centauri b.

Proxima Centauri b is approximately 4.2 light-years away from Earth in the constellation of centaurus, making it the closest exoplanet of the Solar System. Proxima Centauri B is approximately at least 1.3 times the Earth with its circulation period of approximately 11.2 Earth from approximately 0.05 AU lengths. Guess this planet was announced by the European Southern Observatory on August 24, 2016. Proxima Centauri b was discovered using the radial velocity method.

The apparent longing of the orbit of Proxima Centauri b has not yet been measured. The minimum amount of this planet is 1.27m⊕, which will be a real mass if it is seen in orbital orbit. The absolute radius of this planet is unknown. If this planet has a rocky structure and the exact density of the Earth, its radius is at least 1.1 R⊕ .Proxima Centauri b can have an icy structure like Neptune. The balance of this planet is 234 K.

The surface temperature of Proxima Centauri b is 3,042 k and it is 4.85 billion years old. Proxima Centauri b converts once every 83 days, and has a luminance of 0.0015 L. Like two big stars in a Triple Star system, this star is rich in metals compared to the Sun, which is usually not found in low-set stars like Proxima. Its metal is 0.21, or 1.62 times the amount found in the Sun's atmosphere. Proxima Centauri b is known as a flare star.

Proxima Centauri b hosts 11.186 days of semi-major axis, at approximately 0.05 astronomical units. Under the leadership of Queen Mary University of Guillem Anglada-Escudé of London, her research confirmed the existence of Proxima Centauri b. A team of scientists believe that they can depict Proxima Centauri b and combine ESPRESSO and SPHERE on VLT to check the atmosphere of this planet for oxygen, water vapor and methane signs.

Many studies have suggested that Proxima Centauri b has very obscure activity to maintain the atmosphere and liquid water on its surface for the sun planet. But in a new NASA-led study, a team of scientists has examined various climate conditions that suggest that this planet may have enough water to support life. If the rigid radiation of Proxima Centauri b releases 90% of its water, it will also have enough water to have the ocean. It can also be formulated with thick hydrogen holes, which can be left behind the "living core" of the atmosphere.

Proxima Centauri b rotates in its star zone, which means that it is only a reasonable distance to get enough surfaces to keep its surface above the freezing temperatures of the water. Proxima Centauri b is estimated to have approximately 12% of the Sun's mass. Proxima Centauri is believed to have a surface temperature of about 3,042 k, which is as warm as 55% of the sun. These red stars extract far less energy than the larger stars; its luminosity is less than one percent.
