Timeline of close approaches less than one Lunar distance from the Moon in 2015

• Asteroids approaching Earth not only move faster, but are brighter and are easier to detect with modern surveys due to these factors
• Asteroids approaching closer to Earth are higher priority to confirm, and only confirmed asteroids are listed with a lunocentric approach distance
• Those which make close approaches to the Moon are frequently lost in its glare, making them harder to confirm, and are more easily discovered during the new Moon, when the Moon is too close to the Sun for any asteroids to be detected while they are near to the Moon anyway.
