## How big is all the planets put together?

The average Earth-Moon distance is 384,400, and the total of the planets’ average diameters is 380,016. That difference is 4,384 km, very close to their figure. But that doesn’t include subtracting the radii of the Earth and Moon! When you do that (getting 376,000 km or so, remember) the planets don’t fit.

What are the sizes of the planets from smallest to largest?

To ensure that the list stays stuck, just think of something along the lines of “Mercury Met Venus Every Night Until Saturn Jumped.” Essentially, this indicates that the size of the planets in order from smallest to largest is Mercury, Mars, Venus, Earth, Neptune, Uranus, Saturn, and Jupiter.

What is the diameter of all 8 planets?

Distance of the planets from the Sun

Planet Distance from the Sun Diameter
Mercury 57,910,000 km (0.387 AU) 4,879 km
Venus 108,200,000 km (0.723 AU) 12,104 km
Earth 149,600,000 km (1.000 AU) 12,756 km
Mars 227,940,000 km (1.524 AU) 6,805 km

### Which two planets are almost of the same size?

Both planets have almost the same size and density and Venus is only a 30% closer to the Sun than Earth.

How many Earths can fit in the moon?

Size and Distance The Moon is an average of 238,855 miles (384,400 kilometers) away. That means 30 Earth-sized planets could fit in between Earth and the Moon.

How long did it take for New Horizons to reach Pluto?

9.5 years
The \$720 million New Horizons mission launched in January 2006, speeding away from Earth at a record-breaking 36,400 mph (58,580 km/h). Even at that blistering pace, it still took the probe 9.5 years to reach Pluto, which was about 3 billion miles (5 billion km) from Earth on the day of the flyby.

#### What is the biggest planet in the Universe 2020?

Jupiter
The largest planet in our solar system by far is Jupiter, which beats out all the other planets in both mass and volume. Jupiter’s mass is more than 300 times that of Earth, and its diameter, at 140,000 km, is about 11 times Earth’s diameter.

Is there a planet bigger than the Sun?

Explanation: 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. Logically, then the largest planet by mass could only be about 12 times the mass of Jupiter. The Sun has about 1000 times the mass of Jupiter.

What do you notice about the size of the planets?

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. The outer planets are called gas giants and have a diameter of greater than 48,000 kilometers.

## What planet is 1500 miles in diameter?

Pluto averages an astounding distance of 3,670,050,000 miles from the Sun. It is very small 1500 miles in diameter, placing it even smaller than seven of the moons found in the solar system.

What two planets are closest to each other?

Mercury (above) is the closest planet to Earth — in fact, it’s the closest planet to every other planet. This is startling because we all have a built-in misconception about the layout of the solar system. It’s true that Venus orbits the sun between Earth and Mercury.

What are 3 things the inner planets have in common?

The Inner Planets All are solid, dense, and rocky. None of the inner planets has rings. Compared to the outer planets, the inner planets are small. They have shorter orbits around the Sun and they spin more slowly.

### How big are the planets in the Solar System?

Earth – 3,959mi (6,371km) radius; Mars – 2,106mi (3,390km) radius; about half the size of Earth; Jupiter – 43,441mi (69,911km) radius; 11x Earth’s size; Saturn – 36,184mi (58,232km) radius; 9x larger than Earth; Uranus – 15,759mi (25,362km) radius; 4x Earth’s size; Neptune – 15,299mi (24,622km) radius; only slightly smaller than Uranus

How are the middle two planets similar in size?

The middle two planets, Venus and Earth on the other hand, are very similar in size (Venus has a diameter of 12,100km to Earth’s 12,800km) and have a similar composition, mass and density. However, Venus’ position slightly closer to the Sun has resulted in a ‘runaway greenhouse effect’ creating a scorching,…

How to study the size and distance of planets?

Make sure students understand that the distances between the planets are very large compared to the sizes of each planet. This makes it extremely difficult to create an exact scale of our solar system, so this activity will focus on the distance comparison. 5. Have groups create models of relative planetary distances.

#### Why does the Earth weigh different than other planets?

When you stand on a scale, what it’s actually doing is measuring how hard Earth’s gravity is pulling on you. If you were to step onto a scale on another planet, it would say something different than it does here. That’s because the planets weigh different amounts, and therefore the force of gravity is different from planet to planet.
