The smallest known galaxy, Segue 2, has an approximate radius of 1.05 × 1015 kilometers. Use the conversion factors 1 light-year = 9.5 × 1012 kilometers and 1 parsec = 3.262 light-years to convert this distance from kilometers to parsecs.

Answer:

  • 33.88 parsec

Explanation:

Given:

  • 1 light-year = 9.5 × 10¹² kilometers
  • 1 parsec = 3.262 light-years

Convert parsec to km:

  • 1 parsec = 3.262 * 9.5 × 10¹² = 30.989 × 10¹² = 3.0989 × 10¹³

Find the radius of Segue 2 in parsecs:

  • 1.05 × 10¹⁵ / 3.0989 × 10¹³ =
  • 105 × 10¹³ / 3.0989 × 10¹³ =
  • 105/3.0989 =
  • 33.88 parsec
