Draconid Meteor Shower May Burst Into Meteor Storm – Shooting Stars Can Shoot Down Satellites
- nemesis maturity Published on Oct 3, 2018
The October Draconids is an established meteor shower that occurs annually around the 9th of October. The shower was linked in 1926 to the Jupiter-family comet 21P/Giacobini-Zinner, known to evolve on a perturbed and “erratic” orbit. Although the annual activity of the shower is usually low (a few visual meteors per hour), the Draconids produce episodic outbursts (e.g. in 1985, 1998, 2005 and 2011) and meteor storms. In 1933 and 1946, the Zenithal Hourly Rate (ZHR) of the shower reached a level of around ten thousand meteors per hour. In 2012, a completely unexpected Draconid storm was detected by the Canadian Meteor Orbit Radar (CMOR), with an equivalent ZHR reaching 9000 meteors per hour.
The irregularity of these shower displays, caused in large part by the frequent perturbations experienced by the orbit of the comet parent, make the October Draconids among the most challenging meteor showers to predict. The predicted path of the Earth through the debris streams of comet 21P/Giacobini-Ziner is favorable for a major storm, similar to what has been seen in previous years. Some experts predict low Draconid activity, with a maximum of less than a few tens of meteors per hour around 8th to 9th of October. At the L1 and L2 Lagrange points, however, the flux estimates suggest a “meteoroid storm.”
Some reports say NASA is even considering the potential risk of damage to the Discover spacecraft and other satellites due to meteor impacts. The L1 region hosts a significant number of active spacecraft (e.g. SOHO, ACE, GGS and DSCOVR) that might be impacted by meteoroids released by the comet in 1946. The meteroid flux around the ESA’s Gaia spacecraft, orbiting around the L2 region, is particularly significant. The satellite risks to be impacted by large Draconid meteoroids, travelling with a velocity of about 20 km/s. Mission operators at the European Space Agency say they will command the spacecraft to rotate and shield itself to avoid any damage.
Get ready for a spectacular night sky light show! Even for a major outburst of shooting stars. The Draconids will be most visible between sunset and midnight when the constellation Draco is at its highest point. The shower will appear brighter in darker locations, so stargazers are advised to travel to the countryside for the best views.

The Unexpected 2012 Draconid Meteor Storm
- Will the fulfillment of Revelation 12:3-9 be this year? You decide. I am still expecting/awaiting the giant meteor shower.

Comet 21P is on track to cross the Earth’s path just three weeks ahead of our planet’s arrival on October 8, 2018. This has happened before! In 1933, it caused a meteor storm – warning Europe of Hitler’s rise to power. In 1946, it caused a second meteor storm – warning America of the rise of the United Nations and the One World Governmental System. It is about to cause a third, and final, meteor storm this year – and the threat it appears to be warning us about is too evil to even contemplate!
