SUMMARY

The distance between the star systems Sirius and Alpha Centauri is 9.5 light-years. From the perspective of Alpha Centauri, Sirius appears as a tight double star with Betelgeuse, located less than a degree apart in the sky. This information is crucial for authors crafting realistic science fiction narratives involving interstellar travel.

PREREQUISITES
  • Understanding of light-years as a unit of astronomical distance
  • Basic knowledge of star systems and their relative positions
  • Familiarity with astronomical observation techniques
  • Awareness of science fiction narrative elements
NEXT STEPS
  • Research the characteristics of Sirius and Alpha Centauri star systems
  • Explore the concept of stellar parallax for distance measurement
  • Learn about the significance of Betelgeuse in astronomy
  • Investigate realistic interstellar travel concepts in science fiction
USEFUL FOR

Science fiction writers, astronomers, and enthusiasts interested in the distances and relationships between star systems.

9,5 ly.
Incidentally, viewed from Alpha Centauri, Sirius is a tight double of Betelgeuse (less than a degree distance).

Thanks for the answer and the extra tip. Now I know it's 'realistic' for my starship to change destinations.
