Imagine that you have received six pictures of six different children who live near six of the closest stars to the Sun. Each picture shows a child on his or her 12th birthday. The pictures were each broadcast directly to you (using a satellite) on the day of the child's birthday. Note the abbreviation "ly" is used below to represent a light-year.
Eugene lives on a planet orbiting Ross 154, which is 9.5 ly from the Sun.
Max lives on a planet orbiting Barnard's Star, which
is 6.0 ly from the Sun.
Crystal lives on a planet orbiting Sirius, which is 8.6 ly from the Sun.
Sydney lives on a planet orbiting Alpha Centauri, which is 4.3 ly from the Sun.
Kelle lives on a planet orbiting Epsilon Eridani, which is 10.8 ly from the Sun.
Mitch lives on a planet orbiting Procyon, which is 11.4 ly from the Sun.
When you received Mitch's broadcast, how old was he?
