In summary, scientists have recently discovered a new solar twin, HD 98618, which is 126 light years away. Although this distance makes communication difficult, it is close enough for potential detection of habitable planets. Another solar twin, 18 Scorpii, was also mentioned in the article, but its distance was not specified. However, according to an external source, 18 Scorpii is significantly closer.

I see from the above link that we have found a new solar twin, HD 98618. It is 126 light years away. Too far away for meaningful communication (unless we are willing to wait 250 years for an answer), but close enough that we could one day at least detect habitable planets.

The article mentioned another one, 18 Scorpii, but it does not say how far away it is.

Does anyone know?

TIA

18 Scorpii is closer, a lot closer: http://www.solstation.com/stars2/18sco.htm
 

FAQ: How close is 18 Scorpii, the other solar twin?

How far away are solar twins from Earth?

Solar twins are stars that have similar mass, temperature, and chemical composition to our own Sun. They can be found at varying distances from Earth, with the closest known solar twin being 20 light years away in the constellation of Cassiopeia.

How do scientists determine the distance of solar twins?

Scientists use a variety of methods to determine the distance of solar twins, including parallax measurements, spectroscopic parallax, and photometric parallax. These techniques involve measuring the apparent brightness and motion of the stars, as well as their spectra, to calculate their distance from Earth.

Are solar twins the same distance from Earth?

No, solar twins can be found at varying distances from Earth. This is because they are not all formed in the same location or at the same time. Their distances can also change over time due to their orbital paths around the galaxy.

How do scientists find solar twins?

Scientists use telescopes and other instruments to observe and study stars in our galaxy. They look for stars with similar properties to our Sun, such as mass, temperature, and chemical composition, to identify potential solar twins. They also use data from space missions, such as the Kepler mission, to identify solar-like stars that may be good candidates for further study.

Why are solar twins important to study?

Studying solar twins can provide valuable insights into our own Sun and the formation and evolution of stars. By comparing solar twins to our Sun, scientists can better understand the processes that occur in our own star and how it may change over time. Additionally, solar twins may also host planets that could potentially be habitable, making them important targets in the search for extraterrestrial life.
