During the month of June, shortly before the rise of the Sun, we can see Venus resplendent along with Mars, Jupiter and Saturn. As the month progresses, Mercury and Moon will be involved in placement. There is also Uranus and Neptune, but you need a telescope to see them.
dawn between planets
The planets continue to provide us with beautiful spectacles at dawn in June. We have four morning stars this weekend. If we look to the east at about 6 o’clock, we can see, from low to high altitude, a very bright Venus near the horizon, followed by a very intelligent Mars, the brilliant Jupiter and finally, Saturn of a similar brightness. Shining together for Jupiter. Mars.
The scene is preceded by gorgeous colors that are accentuated as the break of dawn. The sky will be progressively brighter and the contrast of the planets against the background will be less, the Sun will rise at 6:45 (Peninsular Time) and its brightness will then obscure all the other stars.
This weekend we have a crescent moon, it can be seen in the west at the beginning of the night. Ophiuchus will have a full moon on the 14th, the so-called ‘strawberry moon’ in Amerindian cultures.
In the second fortnight of the month, the setting moon will be visible before sunrise in the east and will make beautiful conjunctions with various planets. On 18th and 19th it will be close to Saturn, on 21st it will be next to Jupiter and on 22nd it will be close to Mars. But the most beautiful coincidence will be on Sunday 26th, when the thin edge of the waning Moon will be very close to Venus and on Monday 27th when it will be next to Mercury. Amavasya will be on 29th.
Mercury will become visible from June 15, very low in the east-northeast, with a lower elevation and more to the east than bright Venus. Thus, in the second half of the month we will see 5 planets with the naked eye.
In addition, the giants Uranus and Neptune are also located in the same part of the sky, but they are so distant and faint that a telescope is needed to see them. However, we can imagine them in their positions (marked with arrows in the attached image), well aligned with other planets that point to the elliptical.
distance and brightness
The proximity of apparent positions in the sky can be misleading because the planets are actually at very different distances. Mercury is now about 105 million kilometers away, while both Venus and Mars are about 200 million kilometers apart, twice as far away from Mercury. However, Venus is now moving away from Earth, while Mars is getting closer and brighter as it approaches its opposition on December 8.
Jupiter and Saturn are, respectively, 5 and 9.4 times farther from the Sun (remember that the distance from Earth to the Sun is about 150 million kilometers). Saturn will be in opposition on August 14, giving us the optimum time to view its spectacular rings. Uranus and Neptune are 20 and 30 times farther from the King Star, respectively. In other words, distant Neptune is now about 4.5 billion kilometers from Earth.
They appear with very different luminosity because of the difference in their distances and the characteristics of the planets. If we take the bright Venus as a reference, and in decreasing order of brightness, it turns out that Jupiter is 4 times less luminous, Mercury 20 times less, Mars 52 times, Saturn 63 times, Uranus 8,300 times and Neptune 48,000 times less. , with respect to all Venus. Thus it makes sense that we can see neither Uranus or Neptune with the naked eye.
in the zodiac
These scenes take place between the zodiac constellations of Capricorn, Aquarius and Pisces. As the days progress, the planets will gradually change positions, moving closer and farther from each other, describing a kind of dance that will climax when the Moon joins them in the second fortnight of the month.
So it’s worth looking east at these June sunrises to consider the 7 planets in the sky that make up the entire family of the Solar System’s largest bodies, with Earth beneath our feet.
