数学题：旅行者号1号（Voyager 1）在哪里？

Math Problem: Where is Voyager 1?

习题集 | 6-12+年级 | 2026年11月中旬，旅行者号（Voyager）将运行至距离地球（Earth）超过一个光日（light day）的位置。这意味着以光速传播的无线电信号需要约24小时才能到达探测器，因此从地球发送的任何指令都需要整整一天才能送达，而任何响应也需要一天时间才能传回。那么，旅行者号1号距离地球到底有多远？在这一系列引人入胜的数学题中，学生们受邀利用易于融入课堂教学的技能，来拆解“一个光日究竟有多远”这一问题。

Problem Set | Grades 6-12+ | In mid-November 2026, Voyager will pass beyond one light-day away from Earth. That means radio signals traveling at light speed will take about 24 hours to reach it, so that any command sent from Earth takes a full day to arrive, and any response takes another day to get back. So how far is Voyager 1 from Earth? In this engaging series of math problems, students are invited to break down the question of just how far away one light-day is using skills which are easily integrable into a classroom curriculum.
