This only happens once every 11 years, but from time to time, the five planets to the naked eye are visible at the same time, towards the Sun, but sometimes Mars or even Venus may appear smaller. Martin Dolan
From the point of view of humanity, the Sun and the Moon still dominate the sky of the Earth

They surpbad all in terms of brightness, with superior appearances in terms of angular size: about 30 ((arc-minutes): a half-degree
On July 21, 2018, Fernando Cabririzo took a mosaic of the Moon and a number of astronomical objects, using the same telescope and the same camera. You can see the snapshots of the true relative size between the Moon and all the planets except Mercury, which was missed because of the clouds near the horizon. The ISS and Pluto were also captured. Fernando Cabrerizo (Tiedra Astronomical Center)
All the planets in our solar system are only a little larger than the Moon, but much farther.
The eight planets of the Solar System. Their relative real sizes are shown on the scale, but their distances are not. When the two factors are correctly combined, we can learn what is the apparent angular size (and size) of each planet seen from Earth. Wikimedia Commons user WP
When they are closest to the Earth, they seem to be the largest
Orbits of the inner and outer planets, all obeying Kepler's laws. When the Earth and another planet intersect in orbit, they reach the closest approach and appear large one to the other. When they cross each other on opposite sides of the Sun, they seem the smallest. Mars, followed by Venus, knows the greatest relative variations between the size of the perigee and the apogee.

But their angular sizes all vary according to the orbit of the planets.
The best way to see Mercury is from a large telescope, as dozens of stacked images (left, 1998, and center, 2007) in the infrared can reconstruct, or actually go to Mercury and image directly (right), as did the Messenger mission in 2009. The smallest planet in the solar system, its proximity to the Earth means that it always appears more great than Neptune and Uranus. R. Dantowitz / S.Teare / M. Kozubal
Mercury, the smallest planet, ranges from 4.5 "to 13", where 1 "(second of arc) is 1 / 3600th of degree.

Voyager 2 flew by both Uranus (R) and Neptune (L), and revealed the properties, colors, atmospheres and ring systems of both worlds.Neptune always seems smaller, angular in size, than Uranus seen from Earth, even though it's slightly larger world. NASA / Voyager 2
Their much greater distances from the Earth badure that.
Frost, ice caps and clouds are some of the aquatic characteristics Features unfortunately are not visible today, unfortunately, because of the huge dust storm that is rampant on the red planet. Its angular size, which varies by more than a factor of 7, highlights the greatest differences between the closest and the farthest appearance of any planet in the solar system NASA, ESA, and The Hubble Heritage Team (STScI / AURA) [19659002] Mars experiencing the largest relative variation in angular size, from 3.5 "to 25.1"
One of Cbadini's most spectacular mosaic images of Saturn, this 2016 view shows the North Pole, the rings, the shadow of the planet, and the almost fully illuminated face of the most visible world of our solar system. The radius of Saturn is about 60 000 km, but if you include the main rings, they extend over 140 000 km. With the rings included, Saturn may appear even larger than Jupiter, although it is twice as far away as the largest planet in the solar system. NASA / JPL / Space Science Institute
Saturn, the second largest planet, ranges from 14.5 "to 20.1", but if you include its main rings, becomes huge, extending from 33.8 " at 46.9 ".
A comparison of the size of the Earth and Jupiter shows how much the largest gaseous giant in our solar system is compared to Earth. But it is not always the largest planet, in terms of angular size, from our point of view. NASA; Jupiter is the largest planet, living far enough away from Earth.
Jupiter, photographed in 2004 from Earth, sometimes has a dark circle, as one of its moons casts a shadow over its atmosphere. . Here, Ganymede, the largest moon in the solar system and a world even larger than Mercury (but smaller than Mars), has its shadow over its Jovian parent. (Jamie Cooper / SSPL / Getty Images)
For angular size, it is between 29.8 "and 46.9".
An infrared view of the night side of Venus, by the Akatsuki spacecraft. Its brightness is greater than any other planet seen from Earth, and it approaches our world closer than any other planet. When it is on the other side of the Sun, only a few other planets seem smaller. ISAS, JAXA
Venus, our sister planet, is closest to Earth, ranging from 9.7 "to 66.0". 19659027] Galileo's original sketches (1610) of the Venus phases were made very shortly after the telescope was turned to the sky. Astronomers with a very good vision, even before the invention of the telescope, had claimed to see a crescent shape in Venus when it was closest to the Earth Wikimedia Commons user Fernando de Gorocica
Humans with an exceptional vision, Venus approaches the nearest, can barely discern its crescent phase without telescope.
