There is no easy way to say this! Scientists recently found that extrasolar planets leaving the galaxy can travel at speed of up to 30 million miles (48.2 million kilometers) per hour. This means that only subatomic particles leave the Milky Way at higher speeds.
These extreme velocities were unexpected. In 2005, r... |
