In the first episode of Astro Squad, Tara and her daughter Selena discuss their love for space and planets. They start by introducing the 8 planets in our solar system, including the dwarf planet Pluto, and other objects like asteroids and comets. Selena expresses her interest in learning more about the planets, so they discuss each one starting with Mercury, the smallest planet, and moving on to Venus, the hottest planet. They also touch on Earth, the only known planet that can support life, and Mars, the "Red Planet" that scientists believe may have had life on it. Join Tara and Selena as they explore more about space and planets in future episodes of Astro Squad!
