[EN VIDÉO] 9th planet in the Solar System?
Astronomers are convinced of this. It would be a 9th planet within the boundaries of the Solar System!

For several weeks it is necessary to get up early to attend conjunctions of planets and other celestial displays.lunar eclipse and shooting star storm tau Herculites (last Monday) !

Now, a week later Mars passed Jupiter At dawn, in a corner of the sky, at the end of the night, the five planets of the solar system appear together to the east. Five perfectly visible planetseyelash nude, including high gloss Jupiter and Venus. Of course, this year isn’t the first time we’ve admired them. gathered at the same timebut the novelty for the coming weeks is that they are presented in order of actual distance—if it can be called that way.

Mercury is currently the closest planet to Earth

So when you put nose When you go out after 4 am, will you see yourself lined up on the imaginary line of the city?ecliptic (the plane of the orbits of the planets) on the horizon in order from lowest to highest: Venus, Mars, Jupiter and Saturn. Mercury also, but this Friday, June 3, it arrives just before sunrise and will therefore still be very low, very difficult to discern in the flaming flashes of dawn. The higher you go, the better next week will be.

In parentheses, for what we’re talking about Mercuryremember that most asteroid Of the Solar System – again closest to the Sun – it is currently closest to Earth. It’s not Venus or Mars, but rather Mercury at 92 million kilometers (just) versus the 184.6 million Venus and 216 million Mars that separates us from it today, our usual neighbors. Naturally, this changes constantly according to the rhythm of each one’s cycle.

Of the five visible planets, Saturn is the first to ascend around 2 a.m. It is followed by Jupiter and Mars in the east an hour and a half later.

Gift from Heaven: Five Planets Aligned in 2018

article Xavier Demeersmann Released on October 17, 2018

What is wonderful in the sky of this beginning?autumn, very soft. As soon as the sun goes down, you can watch the five brightest planets appear. But they just don’t see…

this summer and especially JulyNearly all the planets of the Solar System were visible during the night, with the exception of Earth, of course. Some without tools, some with the aid of binoculars or binoculars. telescopes. there was even one comet flirting with the limit of visibility to the naked eye (C/2017 S3 Panstarrs) and famous asteroid (Vista)…

Three months later, all the planets reunite at night. When the sky is filled with stars, you can easily see the five brightest as soon as the Sun leaves. Venus and first Mercury at first light twilight. But this is borderline because they are both very low on the horizon and therefore they drift away very quickly. Also, in order to have a better chance of observing them, it is necessary to prefer places with a very clear western horizon.

The moon invites itself in the middle of the aligned planets

A little higher in the sky, you’ll notice Jupiter “lighting up” above the southwestern horizon. this giant planet is one stars of course the brightest of the evening with the Moon and Mars. The Moon imposes itself precisely in the middle of this alignment of the planets. On the evening of October 17, it can be seen spreading between Saturn and Mars. Tomorrow night, true to his course and also slightly “older” than in the first quarter, he invites himself right next to the Red Planet. Watch how the latter continues to shine with vitality. Admittedly, not as much as in midsummer, but its shimmering glow still pierces the night.

Neptune is also there, further east, in Aquarius. But to distinguish it, it is better to arm yourself with a pair of binoculars or, of course, a telescope or telescope. same for Uranus, another distant planet that these days comes off the horizon as others sink into it. we also add PlutoIt is considered, dwarf planetis it there too, glowing faintly between Saturn and Mars.

Comets to observe in the autumn sky

Finally remember this Comet 21P/Giacobini-Zinner continues on his celestial journey. He’s near the dazzle now SiriusLarge Dog. One piece of advice: Hoping to see it (on an instrument) wait until the end of the night until it’s high enough in the sky.

Also not to be missed, especially for the next few weeks: 46P/Wirtanen. It is declared as “Comet of the Year”. No less! On December 16, Wirtanen will become the tenth closest comet to Earth since the 1950s, and at that time many experts believed it was visible to the naked eye. For now, he travels discreetly into the depths of the autumn night. constellation Your oven. A beautiful view in perspective.

Beautiful alignment of planets to be observed until February 20

Article by Xavier Demeersman, published January 21, 2016

Notice to all enthusiasts and especially early risers: the five brightest planets can be seen together at the end of the night for a month from January 20 to February 20, 2016. You don’t need an instrument to admire this pretty rare thing. planetary alignment. On certain dates, the waning Moon will shine next to them.

strumcelestial body; star planetswandering star. “The word planet is derived from: planastay“wandering here and there, going astray”” Wroteastrophysicist Daniel Kunth in his book words from heaven (CNRS edition). We know of a handful of these wandering stars in the terrestrial sky, distinguished by so-called “fixed” jointed stars, as our ancestors observed several thousand years ago (in Babylon, China, and possibly elsewhere, and before…). inside constellationwith their mobility. At least, with the naked eye, its movements are detectable in a few cases from one week to the next. One of the ways to make a difference with others lighting fixtures. We now know that these bright spots have a nature. physically different from distant stars (the planets are the daughters of the stars, “children of the Sun”), and that they all follow the ecliptic path through twelve or even thirteen constellations. zodiac (Ophicuhus is the thirteenth), due to their orbit around the Sun.

on the eight planets of the Solar System (and maybe even new According to the latest news), five can be observed without an instrument: Mercury, Venus, Mars, Jupiter and Saturn (remember, they are associated with five of the seven days of the week). pertaining to Uranus and NeptuneTheir great distance with Earth has always prevented them from discerning them with the naked eye.

It’s a pretty rare occasion: at the end of the night between January 20 and February 20, 2016, five of these wandering stars can be seen together. Indeed, once Mercury rises (it is located near the southeast horizon), we can only see with our eyes all these planets lined up in the celestial sphere between southeast and southeast, about an hour before the Sun casts its first rays. and west, southwest.

When the planets align

Of course, to make the most of this relatively rare spectacle (this last happened between December 15, 2004 and January 15, 2005), it’s best to distance yourself from it. light pollution because it damages the brightness of the stars, and pointing at each of these stars, if any, with a tool. For example, with a simple binocular you can distinguish the phases of glowing Venus or the four Galilean moons of Jupiter. Galileo).

It is the latter who opens the ball. Currently, the giant planet emerges from the eastern horizon shortly before 10 p.m. (France metropolitan time) and gives a spectacle to a number of planets.astronomers striped equatorial strips lovers who endure the cold winter, transport her Red point and, of course, the ballet of the moons (visible with binoculars). Four hours later, shortly before 2 am, March red joins him. Next, it’s his turn to enter the scene on Saturn, around 4:45 PM, followed by Venus about an hour later (around 6 a.m.). Finally, when Mercury appears in the dawn light, the five heroes are reunited.

Note that the waning Moon will be next to these planets alternately until February 6th. First gibbous with Jupiter on 27 and 28 January, then on 30 January Virgo (The brightest star in Virgo) appears with Mars in the last quarter on February 1 and shines close to Saturn two nights later on February 3. Finally, beautiful and thin lunar crescents will appear at dawn on February 5 and 6, not far from Venus and Mercury. Let’s add that the most knowledgeable will undoubtedly take advantage of this to try to observe a tiny body of the Solar System: comet C/2013 US10 (Catalina). Nearly visible to the naked eye at the very beginning of this new year due to its activity, the star continues its journey to the edge of the Solar System through the Solar System’s surrounding constellations. Giraffe and the Little Dipper.

To return to the meeting of these five planets that took place at the end of the night, know that if weather or unavailability, you can’t admire them, at the very beginning of the night between 13 and 19 August this summer with a new alignment of the five planets it will be possible to catch up with you. At the same time, many curious people will watch the last breaths of the apocalypse.yearly rainshooting stars between Perseids.
