Wolf 1069 b is a super-Earth exoplanet that orbits the red dwarf star Wolf 1069. It was discovered in 2020 and its discovery was announced in 2023.

Wolf 1069 b is about the same size and mass as Earth, and is tidally locked to its star, similar to how the Moon is tidally locked to Earth. It’s the sixth-closest known Earth-mass planet to orbit within its star’s habitable zone. 

Here are some other details about Wolf 1069 b:

• It has an orbital period of 16 days 
• It’s 1.26 times the mass of Earth 
• It’s 0.0672 AU from its star 
• It’s located about 31.2 light-years from our Solar System 

Wolf 1069 b could potentially sustain life. It has a magnetic field, although it might be weaker than Earth’s. The planet also receives only about 65% of the radiant power that Earth receives from the Sun. 

Liquid water is a key ingredient for life as we know it, making exoplanets within the habitable zone particularly intriguing in the search for extraterrestrial life. 

However, it may take at least a decade for technology to reach the point where we can analyze the planet’s atmosphere and determine its habitability.

The star has 17% the mass and 18% the radius of the Sun, a temperature of 3,158 K (2,885 °C; 5,225 °F), and a slow rotation period of 150–170 days. It hosts one known exoplanet called Wolf 1069 b which could possibly sustain life

Wolf 1069 b is located about 31.2 light-years from our Solar System. 

Wolf 1069 b is considered a potentially habitable planet because it’s located in the habitable zone of its star. It’s one of a small group of targets, along with Proxima Centauri b and TRAPPIST-1 e, that are being searched for biosignatures

Wolf 1069 is a red dwarf star that’s 17% the mass and 18% the radius of the Sun. It has a temperature of 3,158 K (2,885 °C; 5,225 °F), and a slow rotation period of 150–170 days. 

Wolf 1069 is 0.2 times more massive and 0.2 times bigger compared with our Sun

Wolf 1069 b orbits the red dwarf starWolf 1069, also known as Gliese 1253, GJ 1253, or Karmn J20260+585. The star is located in the constellation Cygnus, about 31.3 light-years from Earth. 

Wolf 1069 b orbits the star every 15.6 days, at a distance equivalent to one-15th of the distance between the Earth and the Sun. Because Wolf 1069 is a red dwarf, it’s much smaller, cooler, and dimmer than the Sun. As a result, Wolf 1069 b receives about 65% of the solar radiance that Earth receives

Wolf 1069 b’s location in its star’s habitable zone makes it a prime candidate for liquid water on its surface. If the planet had retained its atmosphere, it’s likely that it would have liquid water and habitable conditions over a large area of its dayside. 

According to a study, if Wolf 1069 b has an Earth-like atmosphere, temperatures could rise as high as 13°C, which would mean liquid water could pool on the planet’s day side. 

Computer simulations using complex climate models conclude that the planet could maintain moderate temperatures and surface liquid water for a wide range of atmospheric conditions and surface types.

According to Big Think, 35% of known exoplanets are “water worlds”. 

According to the National Ocean Service, more than a quarter of known exoplanets may have liquid water. However, most of these would have subsurface oceans like those on Europa and Enceladus. 

According to NASA, a study indicates that 17 exoplanets could have oceans of liquid water beneath icy shells. Water from these oceans could occasionally erupt through the ice crust as geysers. 

According to Scientific American, astronomers found evidence that two exoplanets orbiting a star 218 light-years away are “water worlds”

Wolf 1069 b is a potentially habitable exoplanet that orbits the red dwarf star Wolf 1069. Its location in the habitable zone of its star makes it a prime candidate for liquid water on its surface. 

The habitable zone is the distance from a star where liquid water can exist on a planet’s surface. Wolf 1069 b’s habitable zone is much closer to the star than the habitable zone around the Sun. If Wolf 1069 b has an Earth-like atmosphere, temperatures could reach 13°C, which would allow liquid water to pool on the planet’s day side. 

Wolf 1069 b is about 1.26 times the mass of Earth and 1.08 times its size. It has an equilibrium temperature of -23°C. If it’s a bare, rocky planet, the average temperature on the side facing the star would be -23°C

According to NASA, a habitable planet is one that can support life for a significant amount of time. Some factors that make a planet habitable include: 

• Liquid water 
• Energy source 
• Atmosphere 
• Magnetic field 
• Long-lived star 
• Low-UV radiative environment 
• Relative lack of gas giants 
• Rotation Other requirements for life on exoplanets include:
  • Temperature 
  • Water availability 
  • Light and redox energy sources 
  • UV and ionizing radiation 
  • Pressure 
  • Rain, fog, snow, or RH > 80%:  According to PNAS, life can be inferred by the presence of atmospheric biosignature gases. These gases are produced by life and can accumulate to detectable levels in an exoplanet atmosphere

So far, scientists have not found evidence of life on any other planet than Earth. However, some exoplanets have the potential to support life. 

The chances of life on an exoplanet increase if it’s in the habitable zone of its star. This means the planet’s surface is the right temperature for liquid water to exist. Every known form of life requires liquid water, so planets that are too close or too far from their star are less likely to support life. 

In 2022, astronomers observed a pair of exoplanets about 100 light-years from Earth. They said one of the planets, which has never been seen before, is a strong candidate for supporting life. 

Some say it’s possible for life to exist on Kepler 452-b because it’s similar in distance to its sun as Earth is to our sun. This means it’s in the “goldilocks zone” or “habitable zone”

Proxima Centauri b is the closest potentially habitable planet to Earth, at a distance of about 4.2 light-years. It orbits Proxima Centauri every 11.186 Earth days, which is over 20 times closer than Earth is to the Sun. 

Some studies conclude that the presence of liquid water on the surface of Proxima Centauri b cannot be ruled out. This makes it a viable candidate for a habitable planet. 

Other potentially habitable exoplanets include:

• TRAPPIST-1 e Has a similar density to Earth, and scientists believe it’s the most likely to have water on its surface 
• Kepler-186f Believed to be slightly larger than Earth and have a similar composition. If it has an atmosphere, it could potentially have oxygen and liquid water

With current technology, it would take around 80,000 years to reach Proxima Centauri b. However, technology is advancing rapidly, and it may be possible to reach Proxima Centauri b in decades with the help of nuclear propulsion or solar sail technology. 

A light-year is 9.44 trillion kilometers, or 5.88 trillion miles. Proxima Centauri is 4.24 light-years away, so walking to it would take 950 million years. 

A constant stream of photons from a laser beam could propel a small craft to relativistic speeds, which is around 20 percent of the speed of light. At those speeds, it would only take 25 to 30 years to get to Proxima b. 

According to one source, Voyager 2 would take about 75,000 years to reach Proxima Centauri.

What makes this discovery particularly intriguing is that Wolf 1069 b is potentially a rocky world, at about 1.26 the mass of Earth and 1.08 the size. Wolf 1069 b also orbits in its star’s habitable zone, making it a prime candidate for liquid water to potentially exist on its surface

Yes, astronomers discovered Wolf 1069 b, a potentially habitable exoplanet, only 31 light-years away from Earth. 

Wolf 1069 b is the sixth closest Earth-mass planet to Earth. It orbits a red dwarf star that’s about one-fifth the size of the Sun. 

As of June 2021, scientists have found 59 potentially habitable exoplanets

According to Universe Today, astronomers could detect biologically produced oxygen in the atmosphere of Wolf 1069 b and infer the presence of life from there

According to Universe Today, scientists are developing new ways to detect and study exoplanet atmospheres. These instruments will look for signs of molecules in planetary atmospheres, including possible biosignatures. 

Wolf 1069 b is a potentially habitable exoplanet that orbits a red dwarf star 31.2 light-years away from the Solar System. Despite its close proximity to the star, it only receives about 65% of the power that Earth gets from the Sun. These special conditions make planets around red dwarf stars like Wolf 1069 potentially friendly to life.

A team of astronomers led by Diana Kossakowski of the Max Planck Institute for Astronomy discovered Wolf 1069 b in February 2023. The discovery was made possible by the CARMENES instrument on the 11.5-foot (3.5-meter) telescope at the Calar Alto Observatory in Spain
