There is no difference between the distances
of the orbits of the inner planets and the outer planets. The planets are all equally distanced from each other. Q.
What is special about the spacing of the orbits of the inner planets?
The inner planets are also
much more closely spaced than their outer Solar System counterparts
. … In fact, the radius of the entire region is less than the distance between the orbits of Jupiter and Saturn.
What is the distance of the inner planets?
Name Diameter Distance from Sun | Mercury 4,879 km 57,909,227 km | Venus 12,104 km 108,209,475 km | Earth 12,742 km 149,598,262 km | Mars 6,779 km 227,943,824 km |

Why are the inner planets so much closer together compared to the outer planets?
The inner planets are much smaller than the outer planets and because of this have
relatively low gravity
and were not able to attract large amounts of gas to their atmospheres.
How do the orbits of the outer planets compare to the inner ones?
The four inner planets have
slower orbits
, slower spin, no rings, and they are made of rock and metal. The four outer planets have faster orbits and spins, a composition of gases and liquids, numerous moons, and rings. The outer planets are made of hydrogen and helium, so they are called gas giants.
Which is the only planet that can sustain life?
Nonetheless, Earth is the only place in the Universe known to harbor life.
Which planet is Earth’s nearest neighbor?
Venus
is the second planet from the Sun and Earth’s closest planetary neighbor. Even though Mercury is closer to the Sun, Venus is the hottest planet in our solar system.
What is the orbits of the planets?
The orbits of the planets are
ellipses with the Sun at one focus
, though all except Mercury are very nearly circular. The orbits of the planets are all more or less in the same plane (called the ecliptic and defined by the plane of the Earth’s orbit).
Which of the following is a complete list of the inner planets?
The inner planets, or terrestrial planets, are the four planets closest to the Sun:
Mercury, Venus, Earth, and Mars
. Figure below shows the relative sizes of these four inner planets. This composite shows the relative sizes of the four inner planets. From left to right, they are Mercury, Venus, Earth, and Mars.
Who is the sister of Earth?
Venus
is sometimes called Earth’s twin because Venus and Earth are almost the same size, have about the same mass (they weigh about the same), and have a very similar composition (are made of the same material). They are also neighboring planets.
Which is the identity of the planets?
Since 2004, the IAU has defined a planet by three criteria: it must orbit the
sun
, be large enough to be shaped into a spherical object by gravity, and clear the neighborhood of its orbit (meaning that there are no objects of comparable size and mass around it).
Is Mars inside or outside the asteroid belt?
The planets inside the asteroid belt are termed the Inner Planets (or the Terrestrial Planets): Mercury, Venus, Earth, and Mars. The planets outside the
asteroid belt
are termed the Outer Planets
What do you notice about the size of the planets?
The most common is to
measure the apparent angular diameter of the planet
– how big it looks against the sky – very precisely using a telescope. Combining this with a measure of its distance (deduced from its orbit around the Sun) reveals the planet’s actual size.
Can humans live on any other planet?
Based on his Copernican principle, J. Richard Gott has estimated that the human race could survive for another 7.8 million years, but
it is not likely to ever colonize other planets
.
Is Earth the only planet with life?
The third planet from the sun, Earth is the only place in the known universe confirmed to host life. With a radius of 3,959 miles, Earth is the fifth largest planet in our solar system, and it’s the only one known for sure to have liquid water on its surface. …
Earth is the only planet known to maintain life
.
What is the hottest planet?
Venus
is the exception, as its proximity to the Sun and dense atmosphere make it our solar system’s hottest planet. The average temperatures of planets in our solar system are: Mercury – 800°F (430°C) during the day, -290°F (-180°C) at night. Venus – 880°F (471°C)
