“Second Moon”: Understand the characteristics of the earth’s orbit
In the past year, the Asteroid 2024 PT5 It has been in orbit around the earth for a few weeks, like an almost natural satellite. It is not surprising that it has received the nickname “second moon” or “minilua”. A group of researchers published a study, which analyzes its trajectory and identifies certain characteristics of the heavenly body.
The heavenly body stayed near the earth for a few weeks and left the planet’s orbit on November 25. According to the new study, this stone object Billions of years may have emerged from the moon’s own materialAfter the confrontation it set up some of its craters. The data was collected by the Teed Observatory in Spain.
One The study published Astronomy & Astrophysics by the Scientific Journal revealed that the chemical composition of this “second moon” displays similarities with the lunar material collected during the US Space Agency Apollo missions (NASA).
“There are many evidence that the asteroid has the lunar origin,” said the main author of the article and the University of the Universidated Compilation De Madrid Professor Carlos de la Funte Marcos, in a message to the space.
The characteristics of “second moon”
Before reaching the earth, The object is in Arjuna Awesome BeltAbout 150 million kilometers from the sun. Most of the asteroids in this area follow a trajectory Estate orbit.
Maros explained that some of these astronomical bodies can reach up to 4.5 million kilometers from the ground. Even to classify it as a “second moon”, a eclipse must meet this standard and speed up 3,540 km per hour.
“Minilua” can be followed by two types of paths: one distance, where the planet is in orbit for years or is a brief way to last for days or weeks. Oh Asteroid 2024 PT5 Meets all the criteria to be classified as a “second moon” This is enough in this second case because it has been in orbit of the earth for a few weeks.
After leaving our orbit, the object returned to the asteroid belt, “expelled” by the sun’s gravity disorders. According to Carlos de La Fuente, the data collected by the Teed Observatory can help more detailed studies on the asteroid in future parts on earth.
2024 PT 5 moon billions of years ago, as scientists believe that a stone object was born from the collision There may be other items in Arjuna Belt.
The study explains, “The asteroid goes through the 2024 PT5’s repetitive Kurbital involvement and temporarily captures the events of ‘minilua’. Its visible spectrum is suitable for a SV-type asteroid or material that is taken out of the moon.”
