2 Answers 2. The Moon has an orbital eccentricity of 0.0549, so its path around the Earth is not perfectly circular and the distance between the Earth and the Moon will vary from the Earth's frame of reference (Perigee at 363,295 km and apogee at 405,503 km), see for example second animation explaining Lunar librations in this answer.
The attack was part of the Al-Anfal Campaign in northern Iraq, as well as part of the Iraqi attempt to repel the Iranian Operation Zafar 7. It took place 48 hours after the fall of the town to Iranian army. The attack killed between 3,200 and 5,000 people and injured 7,000 to 10,000 more, most of them civilians.
In Bush's last year in office, the Iraqi civilian death toll was at around 10,000. Under Obama, it hit 20,000 in 2014. And it's still very high. Nearly 19,000 civilians were killed in Iraq between January 2014 and October 2015 -- a toll the United Nations calls staggering in a new report. This is worse than all but two of the worst years under Bush. By Bush's last year in office, the Surge, which Obama opposed, had worked and the violence had died down.
