Astronomers discover ‘inside out’ solar system
The LHS 1903 system has four planets in an unusual order, with a rocky planet forming last in a gas-depleted environment, challenging standard planetary formation theories.
- Astronomers detected an unusual planetary system around a red dwarf star called LHS 1903, with the order of planets being rocky-gaseous-gaseous-rocky instead of the expected rocky-gaseous order.
- The lead author Thomas Wilson explained that rocky planets typically do not form so far away from their host star, suggesting this system formed in a gas-depleted environment.
- This challenges the widely accepted theory that planets form simultaneously in a protoplanetary disc, as the fourth planet in this system seems to have formed after the system ran out of gas.

A planetary system around the red dwarf star LHS 1903 presents an unusual configuration: the outer planet appears to be rocky, despite being in a region where a gaseous world would be expected. The finding, published on February 12, 2026 in Science magazine and backed by a statement from the European Space Agency (ESA), challenges traditional models of planetary formation.In the Solar System, the planets closest to the Sun are rocky and the most…
