Which planet appears to be the largest of the Earth?

It happens only once every 11 years, but occasionally all five planets are visible with the naked eye all at once, and Mercury is always the hardest to spot due to its proximity to Sun, but sometimes Mars or even Venus may seem smaller. Martin Dolan

From the perspective of humankind, the sun and moon are always dominating the earth's sky.

The moon and the sun both have an angle of about one half-degree magnitude, as seen from Earth, with slight deviations due to the elliptical nature of the orbits of the Earth and the Moon.But even the Moon is at a minimum at least 1764 "(arc seconds) in size, far greater than the 66" maximum reached by the largest (Venus) of the planets.

They outshine everything in terms of brightness, with superior appearances in terms of angular size: around 30 "(B ogenminuten): half a degree

On July 21, 2018, Fernando Cabririzo took a mosaic of t The moon and a series of astronomical objects, with the same telescope and the same camera. You can see the snapshots of the true, relative size between the Moon and all planets, except for Mercury, which was missing due to clouds near the horizon. The ISS and Pluto were also captured. Fernando Cabrerizo (Centro Astronomico de Tiedra)

All the planets of our solar system are only slightly larger than the Moon, but much further away.

When they are closest to the earth, they appear the greatest.

Orbits of the inner and outer planets that obey all Kepler's laws. When the Earth and another planet meet in orbit, they reach the next approach and appear relatively large. When they meet on opposite sides of the sun, they appear the smallest. Mars, followed by Venus, experiences the largest relative differences between apparent perigee and apogee size.

But their angular sizes all vary when the planets rotate relatively

The best way to see Mercury is from a large telescope, how dozens of stacked images (left, 1998 and middle, 2007) can be reconstructed in the infrared, or actually go to Mercury and image it directly (right), as the Messenger mission did in 2009. The smallest planet in the solar system, its proximity to the earth means that it always seems bigger than Neptune and Uranus. R. Dantowitz / S. Teare / M. Kozubal

Mercury, the smallest planet, varies between 4.5 "and 13", with 1 "(arc seconds) being 1/3600 of a degree.

Both Neptune (from 2.2 "to 2.4") and Uranus (from 3, 3 "to 4.1")

Voyager 2 flew past both Uranus (R) and Neptune (L), revealing the features, colors, atmospheres, and ring systems of both worlds: Neptune appears smaller and smaller in angular size than Uranus as seen from Earth, though it is the slightly larger world. NASA / Voyager 2

Their much greater distances from Earth ensure that.

Frost, icecaps and clouds are some of the watery features that you can see from a long distance on Mars, these features are unfortunately not visible today and the massive dust storm that is raging on the red planet's angular size, which varies by more than a factor of 7, shows the biggest differences between the nearest and farthest outward appearance of a planet in the solar system. NASA, ESA and the Hubble Heritage Team (STScI / AURA) [19659002] Mars experiences the largest relative variation in the angular size of 3.5 "to 25.1".

One of Saturn's most spectacular mosaics, taken by Cassini, shows this view in 2016 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 Saturn radius is about 60,000 km, but if you include the main rings, they cover 140,000 km. With the included rings, Saturn may even appear larger than Jupiter, even though it is twice as distant as the largest planet in the solar system. NASA / JPL / Space Exploration Institute

Saturn, the second largest planet, ranges from 14.5 "to 20.1", but if you include its main rings, it will be huge, ranging from 33.8 "to 46.9".

Jupiter is the largest planet that is quite far away from Earth.

Jupiter, as photographed by Earth in 2004, occasionally 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 bigger than Mercury (but smaller than Mars), has cast its shadow over his Jupiter parent. (19659014) For the angular size it lies between 29.8 "and 46.9".

Venus, our sister planet, comes closest to Earth, ranging from 9.7 "to a whopping 66.0". [19659027] Galileo's original (1610) sketches of the Venus phases were made shortly after the telescope was turned to the sky. Astronomers with very good vision, even before the invention of the telescope, had claimed to see a crescent-shaped shape for Venus when it was closest to Earth. People with exceptional vision, at Venus & # 39; next approach, can hardly recognize its crescent phase without a telescope.
