# Xo, Exoplanet - Hardcover

by **Deborah Underwood** (Author), **Jorge Lacera** (Illustrator)

**"When the planets spot something new in the galaxy, they start a letter-writing exchange that gets a little heated (for a planet) over just who gets to be called what and why. This funny fiction also teaches about planets, exo and otherwise." --TODAY**

**From bestselling author Deborah Underwood comes a lively and heartwarming letter writing exchange between all the planets in outer space to show the power of perspective.**

It was an ordinary day for Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune, (and don't forget Pluto, the dwarf planet). The planets were circling the Sun, staring into space, until suddenly they spot something else in their Solar System. _What_ could it be? _Who_ could it be? The planets have no idea but they're circling to find out. Whatever it is that something is most definitely, absolutely, without a doubt NOT a planet. So begins an out-of-this-world pen pal exchange between the planets and an exoplanet: _Dear Exoplanet,_ _We are excited to have you in the galaxy!__XO,_ _Planets_ _Dear Planets,_ _It is nice to hear from you! But what is an exoplanet? Does it mean "excellent planet"?__XO,_ _Exoplanet_ Paired with vibrant illustrations from Jorge Lacera, this STEM-friendly story, told mainly through letters, reminds readers what happens when we consider another person's point of view.
