Earth Waves at Cassini on July 19, 2013. From more than 40 countries and 30 U.S. states, people around the world shared more than 1,400 images of themselves as part of the Wave at Saturn event organized by NASA's Cassini mission. The Cassini team created this image collage as a tribute to the people of Earth. (Credit: NASA/JPL-Caltech/People of Earth)

India's Mars Orbiter Mission (MOM) was in Earth orbit, being boosted to an orbit to get it to Mars. This was also a good chance to do some systems tests. The Mars Color Camera took a picture of Earth. It's focused on the Indian subcontinent. (Credit: ISRO)
Scientists Discover the First Earth-sized Rocky Planet
Kepler-78b compared to Earth. It's 1.2 times the size of Earth and 1.7 times more massive, giving it the same density. It's probably also mostly rock and iron, but it orbits its star every 8.5 hours. Its star is slightly smaller and less massive than the sun and is located about 400 light-years away in the constellation Cygnus.
