Which of the following correctly lists the planets in the solar system from the smallest to the largest in terms of diameter?

Jupiter is the largest planet in the solar system at 139,822 km in diameter. This means that Jupiter is actually more than 28.5 times larger in diameter than the smallest planet, Mercury. 2. Saturn measures out to be 116,464 km in diameter.

Which has the largest diameter?

Largest dwarf planet: Pluto is the largest dwarf planet, with a diameter of 1,473 miles (2,370 km).

What are the 4 smallest planets?

If we put our planets in ‘size order’ they would be listed as the following, from large to small: Jupiter, Saturn, Uranus, Neptune, Earth, Venus, Mars, and Mercury. Since we lost Pluto as an official planet, it appears that Mercury is now considered the smallest planet in the solar system.

What planets are bigger than the sun?

To begin with planets, as that is the easiest question to answer, there are no planets bigger than the sun or even close to the size of the Sun. At about 13 times the mass of Jupiter a planet becomes what is referred to as a “brown dwarf”. These objects are really small stars, as fusion begins at this point.

Is Earth the 3rd smallest planet?

The smallest planet in our solar system is Mercury and the largest planet is Jupiter.

Is Mercury the smallest planet?

Mercury is the smallest planet in our solar system. It’s just a little bigger than Earth’s moon. It is the closest planet to the sun, but it’s actually not the hottest. Venus is hotter.

What planets are bigger than Earth?

The Latest

  1. Mercury. Mercury—the smallest planet in our solar system and closest to the Sun—is only slightly larger than Earth’s Moon.
  2. Venus. Venus spins slowly in the opposite direction from most planets.
  3. Earth.
  4. Mars.
  5. Jupiter.
  6. Saturn.
  7. Uranus.
  8. Neptune.

What blood vessel has the largest diameter?

All arteries of the systemic circulation branch from the aorta (this is the largest artery of the body, with a diameter of 2-3 cm), and divide into progressively smaller vessels.

Are all the planets the same size?

Our solar system includes the sun and eight planets that orbit around the sun. The smaller, inner planets include Mercury, Venus, Earth, and Mars. The inner planets are rocky and have diameters of less than 13,000 kilometers. The outer planets include Jupiter, Saturn, Uranus, and Neptune.

How big is the moon compared to mercury?

Mercury’s diameter is 3,030 miles (4,878 km), comparable to the size of the continental United States. This makes it about two-fifths the size of Earth. It is smaller than Jupiter’s moon Ganymede and Saturn’s moon Titan. But it’s not going to stay that size; the tiny planet is shrinking.

Is Earth the 3rd largest planet?

Uranus is the third-largest planet and the least massive of the four outer planets. It is tilted almost onto the plane of its orbit. Neptune is the fourth-largest planet, as smallest of the four outer planets, but third-most massive. It has one big retrograde moon and many small ones.

Is Pluto still a planet?

In 2005, Eris, a dwarf planet in the scattered disc which is 27% more massive than Pluto, was discovered. This led the International Astronomical Union (IAU) to define the term “planet” formally in 2006, during their 26th General Assembly. That definition excluded Pluto and reclassified it as a dwarf planet.

Are there 12 planets?

[1] The eight planets are: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune.

Is the sun bigger than the Jupiter?

Jupiter is much larger than Earth and considerably less dense: its volume is that of about 1,321 Earths, but it is only 318 times as massive. Jupiter’s radius is about 1/10 the radius of the Sun, and its mass is 0.001 times the mass of the Sun, so the densities of the two bodies are similar.

Is Saturn bigger than the sun?

Saturn is the sixth planet from the Sun and the second-largest in the Solar System, after Jupiter. It is a gas giant with an average radius about nine times that of Earth. It has only one-eighth the average density of Earth, but with its larger volume Saturn is over 95 times more massive.

Is the moon larger than Earth?

The Moon is exceptionally large relative to Earth: Its diameter is more than a quarter and its mass is 1/81 of Earth’s. It is the largest moon in the Solar System relative to the size of its planet, though Charon is larger relative to the dwarf planet Pluto, at 1/9 Pluto’s mass.

What planets have been visited by humans?


  • Mercury.
  • Venus.
  • Mars.
  • Jupiter.
  • Saturn.
  • Earth’s Moon.
  • Moons of Mars.
  • Moons of Saturn.

What four planets are larger than Earth?

The four smaller inner planets, Mercury, Venus, Earth and Mars, are terrestrial planets, being primarily composed of rock and metal. The four outer planets are giant planets, being substantially more massive than the terrestrials.

Is Mars bigger smaller or the same size as Earth?

Mars is approximately half the diameter of Earth, with a surface area only slightly less than the total area of Earth’s dry land. Mars is less dense than Earth, having about 15% of Earth’s volume and 11% of Earth’s mass, resulting in about 38% of Earth’s surface gravity.

How big is the sun seen from Mercury?

The Sun from Mercury. On average, the visible diameter of the Sun on Mercury is 2.5 times as large as it appears from Earth, and its total brightness is more than 6 times as great.

Is Ceres bigger than the moon?

It was roughly one-twentieth the mass of Mercury, which made Pluto by far the smallest planet. Although it was still more than ten times as massive as the largest object in the asteroid belt, Ceres, it had one-fifth the mass of Earth’s Moon.

Is the water on Mars drinkable?

Almost all water on Mars today exists as ice, though it also exists in small quantities as vapor in the atmosphere, and occasionally as low-volume liquid brines in shallow Martian soil. The only place where water ice is visible at the surface is at the north polar ice cap.

What Colour is the sky on Mars?

The normal hue of the sky during the daytime is a pinkish-red; however, in the vicinity of the setting or rising sun it is blue. This is the exact opposite of the situation on Earth. However, during the day the sky is a yellow-brown “butterscotch” color. On Mars, Rayleigh scattering is usually a very small effect.

What is the angular size of the sun as seen from Earth?

= (206,265) d / D arcseconds. Thus, the angular diameter of Earth’s orbit around the Sun as viewed from a distance of 1 pc is 2″, as 1 AU is the mean radius of Earth’s orbit. The angular diameter of the Sun, from a distance of one light-year, is 0.03″, and that of Earth 0.0003″.

Was Ceres ever considered a planet?

Bodies that met the first proposed definition but not the second, such as Ceres, were instead classified as dwarf planets. Ceres is the largest object in the asteroid belt. It is sometimes assumed that Ceres has been reclassified as a dwarf planet, and that it is therefore no longer considered an asteroid.

Was there once a planet between Mars and Jupiter?

Phaeton (or Phaëton) was the hypothetical planet theorized by the Titius–Bode law to have existed between the orbits of Mars and Jupiter, the destruction of which supposedly led to the formation of the asteroid belt (including the dwarf planet Ceres).

Why is haumea not a planet?

Haumea is a plutoid, a dwarf planet located beyond Neptune’s orbit. It is classified as a dwarf planet because it is presumed to be massive enough to have been rounded by its own gravity into a shape in hydrostatic equilibrium, but not massive enough to have cleared its neighbourhood of similarly sized objects.
