Is Saturn a solid planet?
Gas Giant. Saturn is a gas-giant planet and therefore does not have a solid surface like Earth’s.

Is there a planet made of diamonds?
One such planet is PSR J1719-1438 b, companion to a millisecond pulsar. It has a density at least twice that of lead, and may be composed mainly of ultra-dense diamond. It is believed to be the remnant of a white dwarf after the pulsar stripped away more than 99 percent of its mass.
What if Earth was 10 times bigger?
If the hypothetical super-Earth were even bigger, say, 10 times its current mass, dramatic changes could start happening in Earth’s interior. The iron core and liquid mantle would also be 10 times larger, and with more gravity acting on a larger mass, the pressure beneath Earth’s surface would increase.
Who discovered Earth?
Five planets have been known since ancient times — Mercury, Venus, Mars, Jupiter, and Saturn. The first new planet discovered was Uranus. It was discovered by the English astronomer Sir William Herschel in 1781….
| PLANET | DIST. FROM SUN (A.U.) | ORBIT PERIOD (EARTH-YEARS) |

| Neptune | 30.11 | 164.79 |
| Pluto | 39.44 | 248.5 |
Can we live in Venus?
To date, no definitive proof has been found of past or present life on Venus. With extreme surface temperatures reaching nearly 735 K (462 °C; 863 °F) and an atmospheric pressure 90 times that of Earth, the conditions on Venus make water-based life as we know it unlikely on the surface of the planet.
What is the most Earth-like planet found so far?
Kepler-452b. This world, whose discovery was announced last month, is the most Earth-like planet found so far, NASA officials say. Its parent star is very similar to our sun, and the planet orbits
Are there other planets like Earth?
Finding Another Earth. A newly discovered exoplanet, Kepler-452b, comes the closest of any found so far to matching our Earth-sun system. This artist’s conception of a planetary lineup shows habitable-zone planets with similarities to Earth: from left, Kepler-22b, Kepler-69c, the just announced Kepler-452b, Kepler-62f and Kepler-186f.
What is the name of the planet that NASA just discovered?
NASA Discovers New Earth-Like Planet. Kepler 452b was discovered on NASA’s Kepler mission orbiting in the habitable zone around a sun-like star, or the zone in which liquid water could pool on the surface of an orbiting planet, according to a NASA statement.
Is this the only Earth-size planet discovered in a habitable zone?
TOI 700 d is one of only a few Earth-size planets discovered in a star’s habitable zone so far. Others include several planets in the TRAPPIST-1 system and other worlds discovered by NASA’s Kepler Space Telescope.
