SUMMARY

The forum discussion centers on the distance of 18 Scorpii, identified as a solar twin. While HD 98618 is confirmed to be 126 light years away, 18 Scorpii is significantly closer, although the exact distance was not initially provided. A user referenced an external source, SolStation, which indicates that 18 Scorpii is much nearer than HD 98618, suggesting potential for future exploration of habitable planets. The conversation highlights the importance of accurate astronomical data in understanding the proximity of solar twins.

PREREQUISITES
  • Basic understanding of astronomical distances (light years)
  • Familiarity with solar twins and their significance in astrophysics
  • Knowledge of astronomical databases and resources (e.g., SolStation)
  • Awareness of the implications of distance on interstellar communication
NEXT STEPS
  • Research the characteristics of solar twins and their relevance to exoplanet studies
  • Explore the methods used to measure distances to stars, focusing on parallax and other techniques
  • Investigate the potential for detecting habitable planets around stars like 18 Scorpii
  • Learn about the implications of light travel time on communication with distant stars
USEFUL FOR

Astronomers, astrophysics students, and space exploration enthusiasts interested in the study of solar twins and the search for habitable exoplanets.

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
