Risks from outer space

Some risks from space, such as a meteorite impact or a solar storm, are beyond our control. These may occur in our country at any time, either expected or unexpected.

Solar storms can have a major impact on electricity supply, or on the operation of communication networks or navigation systems such as Global Navigation Satellite Systems (GNSS). Meteorite impacts can also have major consequences. Fortunately, the chance of this happening is small.



  • Follow the recommendations of the government.


  • If the solar storm has caused a power outage, check that the food in your fridge and freezer is not spoiled. When in doubt, it is best to throw it away.

Impact and probability

Meteorite impact on Earth. Impact: catastrophic impact. Probability: very unlikelySevere solar storms. Impact: high impact. Probability: possible.In 2018, the National Crisis Center coordinated a large-scale risk assessment for Belgium for the period 2018-2023. Several experts assessed various risks based on their probability and their impact on people, society, the environment and the economy.

For the risk of 'meteorite impact on Earth', the analysis is:

  • Impact: catastrophic impact
  • Probability: very unlikely

For the risk of 'severe solar storm', the analysis is:

  • Impact: high impact
  • Probability: possible

What does the government do?

The Royal Observatory of Belgium studies space weather. They send out daily reports and warnings, e.g. in case of increased solar activity.

In the event of a meteorite impact, municipalities, provinces or the National Crisis Center fall back on their general emergency and intervention plan.
