In this part of the book we describe the rotation of planets and moons of the solar system. Besides providing information on the current rotation rate and orientation of these bodies, we discuss the changes in the rotation speed and orientation on both short and long timescales. We show how information on the planetary interior and dynamics can be determined from observations of changes in rotation and orientation and what we have learned so far.
En primavera empieza el verano y empieza a hacer calor, y en otoño empiezan los árboles a caérseles las hojas y durante el tiempo empieza a hacer un poquito de frío.
