What planet is the outermost of the four inner terrestrial planets?
The inner planets (in order of distance from the sun, closest to furthest) are Mercury, Venus, Earth and Mars. After an asteroid belt comes the outer planets, Jupiter, Saturn, Uranus and Neptune.
Why is Venus the least elliptical?
Venus is summarized as being the least elliptical of all the planets. This is because its revolution is a near perfect circle.
Which planet is Earth most like?
Venus and Mars are the most like Earth, but in different ways. In terms of size, average density, mass, and surface gravity, Venus is very similar to Earth. But Mars is the planet that is most similar to Earth in other ways.
Was Uranus was the ninth body in space to be identified and named?
Uranus was the ninth body in space to be identified and named. The distances in space are based on astronomical units, which are average distances between the Sun and Earth. Like Earth, Mercury has one moon. Venus is more like Earth than any other planet in the Solar System.
What is considered to be the most volcanically active body in our solar system?
The moon Io is the most volcanically active world in the solar system. Io even has lakes of molten silicate lava on its surface.
How many planets have humans landed on?
Only our two nearest neighbours Venus and Mars have been landed on. Landing on another planet is technically challenging and many attempted landings have failed. Mars is the most explored of the planets. Mercury could be landed on but the speeds involved and the proximity to the Sun are challenging.
What planets have humans landed on?
Several Soviet and U.S. robotic spacecraft have landed on Venus and the Moon, and the United States has landed spacecraft on the surface of Mars.
What planet has no seasons?
Mercury Mercury is also the only planet in our solar system without any tilt, so technically lacks seasons. But what it does have is a highly elliptical orbit, creating a version of summer and winter.
Is there another Earth with humans?
The Kepler space telescope identified the exoplanet, and its discovery was announced by NASA on 23 July 2015….Kepler-452b.
| Discovery | |
|---|---|
| Star | Kepler-452 |
| Physical characteristics | |
| Mean radius | 1.5 +0.32 −0.22 R Earth |
| Mass | 5 ± 2 M Earth |
Do any planets have water?
Evidence points to oceans on other planets and moons, even within our own solar system. But Earth is the only known planet (or moon) to have consistent, stable bodies of liquid water on its surface.
Who named planets?
The Romans bestowed the names of gods and goddesses on the five planets that could be seen in the night sky with the naked eye.
Why are there 8 planets instead of 9?
It has a bunch of dirty little snowball objects left over that are orbiting in the Kuiper belt. Some of which get pushed out of their orbits and fly past the sun as comets every now and then. That makes 8 planets.
Is Titan habitable?
Thus, Titan could potentially harbor environments with conditions suitable for life—meaning both life as we know it (in the subsurface ocean) and life as we don't know it (in the hydrocarbon liquid on the surface).
Is the Moon still volcanically active?
This activity was originally thought to have petered out about 1 billion years ago, but more recent evidence suggests that smaller-scale volcanism may have occurred in the last 50 million years. Today, the Moon has no active volcanoes even though a significant amount of magma may persist under the lunar surface.
Which God is Earth named after?
Earth is the only planet not named after a Roman god or goddess, but it is associated with the goddess Terra Mater (Gaea to the Greeks). In mythology, she was the first goddess on Earth and the mother of Uranus. The name Earth comes from Old English and Germanic.
What happens if you commit a crime in space?
It states that any person who is launched into space or on a celestial body is under the jurisdiction and control of the country who put them there.
What planet takes 7 years to get to?
Saturn FAQ – Spacecraft
| Spacecraft | Target | Time |
|---|---|---|
| Messenger | Mercury | 6.5 years |
| Cassini | Saturn | 7 years |
| Voyager 1 & 2 | Jupiter; Saturn; Uranus; Neptune | 13,23 months; 3,4 years; 8.5 years; 12 years |
| New Horizons | Pluto | 9.5 years |
Is there a water in Jupiter?
Jupiter. Jupiter doesn't have a solid surface, but its atmosphere contains water vapor. Jupiter's moons harbor a lot of ice in many forms. Ganymede has water ice on the surface, and likely has a large ocean of salty liquid water deep in the subsurface.
Who discovered Earth?
The first person to determine the size of Earth was Eratosthenes of Cyrene, who produced a surprisingly good measurement using a simple scheme that combined geometrical calculations with physical observations.
What planet can we live on besides Earth?
Kepler-62e and Kepler-62f are thought capable of hosting life. The planet Kepler-69c is located about 2,700 light-years from Earth in the constellation Cygnus. This is an illustration of the planet, which is the smallest yet found to orbit in the habitable zone of a sun-like star.
What planet rains diamonds?
Deep within Neptune and Uranus, it rains diamonds—or so astronomers and physicists have suspected for nearly 40 years. The outer planets of our Solar System are hard to study, however. Only a single space mission, Voyager 2, has flown by to reveal some of their secrets, so diamond rain has remained only a hypothesis.
Who was the ugliest god?
Hephaestus Hephaestus. Hephaestus is the son of Zeus and Hera. Sometimes it is said that Hera alone produced him and that he has no father. He is the only god to be physically ugly.
Who named Earth in the Bible?
God Translations of the Bible into English was one of the earliest recorded use of the name Earth – ” God called the dry land Earth, and the waters that were gathered together he called Seas. And God saw that it was good. “(Genesis 1:10)
Why is Pluto no longer a planet?
The International Astronomical Union (IAU) downgraded the status of Pluto to that of a dwarf planet because it did not meet the three criteria the IAU uses to define a full-sized planet. Essentially Pluto meets all the criteria except one—it “has not cleared its neighboring region of other objects.”
Where is Pluto gone?
Pluto's atmosphere is going through a strange transformation, scientists are finding. The icy dwarf planet, which lies over 3 billion miles (4.8 billion kilometers) away from Earth in the Kuiper Belt, caught astronomers' attention as it passed in front of a star back in 2018.
Is the water on Titan drinkable?
Titan is going to have methane and ethane tainting the ice. And Enceladus and Europa are going to be all kinds of salts and possibly magnesium sulphate, or epsom salts if it's hydrated. So if you drink that water you'll be trotting off to the loo quite soon.
Can humans live on Europa?
Europa's surface is blasted by radiation from Jupiter. That's a bad thing for life on the surface – it couldn't survive. But the radiation may create fuel for life in an ocean below the surface. The radiation splits apart water molecules (H2O, made of oxygen and hydrogen) in Europa's extremely tenuous atmosphere.
Is there lava on the Sun?

What was found on the moon by the Chinese?
China's Yutu 2 rover has made yet another curious discovery during its travels on the far side of the moon, this time turning up a pair of translucent glass globules. The rover's panoramic camera spotted the two glass spheres as it drove across the surface of Von Kármán crater on the far side of the moon.
