The orbit of asteroid 2016 HO3 wok & # XF3; & # x142; the Earth

The orbit of asteroid 2016 HO3 around the Earth (NASA / JPL-Caltech)

It is not as big as our old silver globe, as measured barely a few dozen meters. So you can not see it with the naked eye, but it is our faithful companion, the good and the bad. We are also used to send astronauts to him?

For now has few romantic name, because it is listed in the records of astronomical object as 2016 HO3. Tracked him April 27 of this year, automatic search for asteroids PAN-STARRS1 Hawaii, funded by NASA in defense of our planet by catastrophic collisions with strangers celestial bodies.

2016 HO3 not fragments, measuring from 40 to 100 meters, but certainly we do not threaten. At least for the next few hundred years. We know this because after discovering it also found on older images of the sky and still managed to determine its orbit. Yesterday So NASA announced that technically speaking, the asteroid is in orbit around the Sun, and in resonance 1: 1 with the Earth. This means that orbits the Sun almost exactly one year, as our planet. Therefore, always kept close to it.

Since its orbit is more egg-shaped than the Earth, is for about half a year is closer to the Sun and therefore moves faster ahead of Earth in its journey wokółsłonecznej. But for the next six months it is a bit further from the Sun, which means that it slows down and lags behind the planet. From our, or earthly point of view, this mutual dance looks like an asteroid moved in circles around our planet. - Because the orbit in 2016 HO3 is looped around the Earth and the asteroid does not distance himself too far, it is defined as quasi-moon - says Paul Chodas Center Objects Near Earth at NASA.

This is the mutual dance the asteroid with the Earth moving around the Sun

gravitational interaction with the Earth causes the distance to the asteroid changes from decade to decade, but never moves it more than a hundredfold the distance Earth - Moon. Work is never closer than 14 million kilometers (or 38 times farther than the Moon).

- Our calculations indicate that in 2016 HO3 is in the resonance with the Earth for about a hundred years and remains our stable companion through the centuries - says Paul Chodas. In the near future no one so we do not steal.

This is not the first such case. Earlier accompanied us asteroid 2003 yn107, a speck of a 20-meter diameter, but ten years ago, our paths diverged. On the other hand, for a few hundred years, several other nearby asteroid, including a 5-kilometer Cruithne, it can also be our satellites.

For now, we have close to 2,016 HO3. Until revolves around the Earth, we can get to know, maybe even fly to it (some asteroids are rich in valuable minerals), but definitely worth it called a more human name.

Note ! On Tuesday, the "Election" special edition "Science for Everyone", and attractions in the summer sky, that is how and what to watch during the holiday night. For lovers of heaven and those who want to get started with astronomy.

                             "We have a second moon." No, we have not. This is the conclusion of the articles of the quoted title.

                             And there 'in the near future no one we do not steal, "Kaczynski still do not know ...

                             Oh, please. Today I read about this elsewhere and thought, "Why was not this in Science Election?", No, but I go, and it is. Super.

The great orbit is the H03, this happened. As if he tried very hard to not fall on us.

                             And if so send some sort of tiny electromagnetic boat space with a tiny Polish flag ....

                             'Because its orbit is more egg-shaped than the Earth "- oval / elliptical can?

                             So as a groundhog sitting and wrapped in sreberka ...
Lies and lies only can be read here.

People does not and has never been in space and NASA and holywod together form the beautiful graphics that to be confirmation of everything like they do there.
Think about where they come from four seasons and have been with us forever each year.
since the sun is supposedly 150 million km this hell we would experience no such difference we feel depending on the season.
Flora plants and animals are different in the northern and southern hemispheres. In the south, already below 70 degree practically there are no plants and animals, where at the same height in the north are hundreds of different species.
Earth is not shaking a ball at over 1000mph at the equator but is flat and stationary. The media did not tell you because it's pals those who manipulate us by giving us these beautiful graphics green background, etc.

On youtube there are many movies in English on the subject.
