After more than half a century of speculation, it was confirmed that the Earth was surrounded by two "moons" of dust, nine times larger than our planet.
Scientists have discovered two more moons of earth in addition to the one we have known for so long.
The Earth is not only a moon, she has three The existence of these two extra moons has been hotly debated for more than 50 years, but according to a recent report by National Geographic, Hungarian astronomers and physicists finally provided enough data to confirm that our moon had at least two other companions – all made up of dust.
The team of researchers confirmed their presence through photographs of the Body at a distance of about 250,000 miles – about the same distance as our moon.
The discovery was published in Monthly Opinion of the Royal Astronomical Society.
Information on the newly discovered dust of the moons
- Researchers have long since deduced the presence of clouds of dust moons or Kordylewski
- but the first glimpse of clouds It was observed that in 1961 by the Polish astronomer Kazimierz Kordylewski, according to which the dust clouds were named
- New discoveries indicate that each cloud of Kordylewsky measures about 15 out of 10 wide, or is equal to 30 out of 20 lunar discs in the night sky
- . They are spread over a space. An area that is almost nine times the width of the Earth – about 65,000 km in actual size
- The "moons" of dust are immense, but they are m tiny particles of dust who does not measure a micrometer on
- When the sun is When they hit the dust particles, they shine very faintly, much like the zodiacal light we receive scattered dust between planetary orbits
- These clouds of satellite dust emitting extremely weak light, they are very hard to find in the midst of starlight, sky glow, galactic light and zodiacal light in the sky although they are as close to us as the moon
- The recent study revealing the existence of two "dust moons" has used special polarizing filters on cameras to reveal the light scattered from After the reflection of individual dust particles in clouds
Kordylewski's clouds change constantly
Kordylewski's clouds change constantly. They may be stable in orbit and have existed for millions of years, but the ingredients that make up the clouds – the dust particles – are always exchanged for others.
Some escape gravitation from Earth or Earth. the moon, while others come from interplanetary spaces and meteor showers
How Lagrange points in space helped to find the extra "moons"
The speculations according to which the Earth having several moons succeed one another in the circle of astronomers for years. It was realized that if additional moons existed, they could only do so in stable points in Earth's orbit.
Lagrange Points (source: NASA)
Lagrange points are soft points in a planetary orbit where the force of gravity works. The centripetal force of their orbits is balanced between two opposite celestial bodies.
Thus, an object located at a point in Lagrange will remain fixed at a constant distance from the Moon and the Earth.
In the 1950s, Kordylewski two Lagrange points – L4 and L5 – where he first saw the two clouds of dust orbiting the Earth.
Can these "moons of 19659026" be dangerous or will they help us?
These Huge Clouds Dust could add a lot to space exploration efforts in terms of fuel consumption and safety issues.
Sometimes it is necessary to park satellites at Lagrange points so that the spacecraft consumes a minimum of fuel and can remain in orbit.
The James Webb space telescope will be installed for this purpose at Lagrange point L2 in 2020.
In addition, space agencies are also planning to use Lagrange points as transfer stations for Mars missions.
