SUMMARY

Detecting planets in a solar system similar to ours from a few light-years away is feasible, particularly if the system is viewed edge-on. This orientation allows for accurate measurement of radial velocity changes in the Sun and increases the likelihood of observing planetary transits. The gravitational influence of large planets, especially Jupiter, can be detected with current technologies, but additional details require observing transits.

PREREQUISITES
  • Understanding of radial velocity measurements
  • Knowledge of planetary transits and their significance
  • Familiarity with gravitational influence in celestial mechanics
  • Basic concepts of observational astronomy
NEXT STEPS
  • Research techniques for measuring radial velocity in exoplanet detection
  • Learn about the methods for observing planetary transits
  • Explore the gravitational effects of large celestial bodies
  • Study observational astronomy tools and technologies
USEFUL FOR

Astronomers, astrophysicists, and enthusiasts interested in exoplanet detection and the dynamics of solar systems.

Hi,

With today's technologies, if our exact solar system were at a few light-years from us, could we detect its planets ?

Probably. It depends on the inclination of the orbital plane. If we look at the solar system "edge on" it would be relatively easy, as this view angle allows us to measure the largest changes in the radial velocity of the Sun and would also give us the best chance to see the planets transit cross the Sun.
 
You could detect the gravitational influence of the planets [mainly Jupiter] at such a distance rather easily. You would need transits to tease out further details.
