Travelers In The Night

My Catalina Sky Survey teammate Greg Leonard discovered an asteroid, 2017 EA, which is so tiny that it could pass under a basketball hoop. It missed exploding in our atmosphere by only about 9,000 miles as it streaked between the communications satellites and the surface of our planet high above the eastern pacific ocean. After Greg discovered it, this small celestial visitor was tracked by telescopes in Arizona, New Zealand, and New Mexico before it disappeared into the Earth's shadow. When this tiny space rock emerged from our planet's shadow it was too close to the Sun for further observations by ground based telescopes. However, our observations pinned down it's orbit around the Sun well enough, for astronomers to conclude that it will not come this close to us again during the next six encounters with Earth from 2019 to 2126.
