Astronomers
believe fragments of a mysterious lost world are locked in orbit around Mars.
This
ancient planet may have smashed into the Martian surface during the early days
of the solar system, creating a series of nine asteroids called the Trojans.
“The
Trojans are really a relic from the early life of the solar system, when the
planets were still forming,” Apostolos Christou from the Armagh Observatory and
Planetarium told New Scientist.
Astronomers
now believe the Martian Trojans are all made up of the same material –
suggesting they once belonged to the same planet.
Asteroids
which orbit planets are called Trojans.
They have
been around since the birth of the solar system, when the distribution of
planets, asteroids and comets was very different from today.
About 6,000
Trojans have been found in the orbit of Jupiter and about 10 in Neptune’s.
Mars is so
far the only terrestrial planet known to have Trojan companions which orbit regularly.
The first
Mars Trojan was discovered more than 25 years ago at L5 and named “Eureka” in
reference to the famous exclamation by Ancient Greek mathematician Archimedes.
It has nine
of these satellites, but they all have a mysteriously different structure to
every other space rock in the solar system.
The
asteroids are made up of olivine, which is a mineral that forms in larger
objects that suffered super high pressures and temperatures.
The
scientists, lead by Apostolos Christou and Galin Borisov at the Armagh
Observatory and Planetarium in Northern Ireland, claim this is evidence that the
rocks are the remains of a lost planet.
The ancient
world could even have impacted on our own civilisation, Christou revealed.
He said:
“Our findings suggest that such material has participated in the formation of
Mars and perhaps its planetary neighbour, our own Earth.”
It follows
a new bombshell theory that life on Mars may have been forced underground after
a catastrophic disaster turned the Red Planet into a “frigid desert”.
