Early risers in Melbourne were treated to an unexpected celestial event in the pre-dawn hours, as what initially appeared to be a meteor lit up the sky at around 5:27 am AEDT. However, the truth behind the luminous spectacle was soon unveiled by local astronomers who identified it as a piece of space debris.

Amateur astronomer and scientist Marco Langbroek quickly pinpointed the origin of the sighting, noting on Bluesky that “Starlink-5103 is a match in both position and being in the current TIP window.” This revelation helped clarify that the bright object streaking across the heavens was, in fact, terrestrial in origin.

Nonetheless, the sight of the space junk left a sense of awe among early risers across Victoria. Enthusiastic skywatchers from suburbs such as Hastings, Langwarrin, Sandringham, and Mortlake were quick to capture the moment on camera, documenting the unexpected morning show.

For those wondering how to distinguish space debris from meteors, there are some telling differences. Space junk, often remnants of satellites, typically moves at a slower speed of about eight kilometers per second and travels in a more horizontal trajectory compared to the swift, fiery descent of meteors.

There is an easy way to tell the difference between space junk and meteors.

Space junk from satellites typically travel at a slower pace, at around eight kilometres per second, and move almost horizontally.

Meteors and shooting stars, meanwhile, can travel tens of kilometres per second.

This comparatively leisurely pace means observers can capture space junk on camera.

A growing number of satellites and space debris in orbit around Earth are impacting the night sky.

As of December 2025, there were currently 9357 Starlink satellites – owned by billionaire Musk’s company SpaceX – in orbit.

The Starlink satellites orbit around 550 kilometres above the earth and are designed to stay in the sky for between five and seven years.

Musk previously described Starlink as “rebuilding the internet in space”.
