If my daughter is the first to set foot on Mars, will she and her crewmates have the honor of creating and naming new constellations?

ROB BIGNELL, IOWA CITY, IOWA
Unfortunately, your daughter will have to travel much farther than Mars to notice a change in the shape of constellations. The stars are so distant that, even from cold Pluto, the constellations will look the same as they do here on Earth. She would have to travel more than 77 times Earth's distance from the Sun (for a distance of 7.2 billion miles) before noticing even the slightest change in the position of Proxima Centauri, which lies 4.22 light-years away and is the closest neighboring star.
