What planet has diamond rain?
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.
Is there gold on moon?
Digging a little deeper than the Moon’s crust, scientists have discovered that the Moon does indeed have a number of precious metals such as gold and silver.

Do all 9 planets ever align?
The planets in our solar system never line up in one perfectly straight line like they show in the movies. … In reality, the planets do not all orbit perfectly in the same plane. Instead, they swing about on different orbits in three dimensional space. For this reason, they will never be perfectly aligned.
Which planet we can see from Earth with naked eyes?
Only five planets are visible from Earth to the naked-eye; Mercury, Venus, Mars, Jupiter and Saturn. The other two— Neptune and Uranus—require a small telescope.

Because of the orientation and tilt of their orbits, the eight major planets of the Solar System can never come into perfect alignment. The last time they appeared even in the same part of the sky was over 1,000 years ago, in the year AD 949, and they won’t manage it again until 6 May 2492.
How long can the earth survive without the Sun?
A relatively simple calculation would show that the Earth’s surface temperature would drop by a factor of two about every two months if the Sun were shut off. The current mean temperature of the Earth’s surface is about 300 Kelvin (K). This means in two months the temperature would drop to 150K, and 75K in four months.
What rains on Mars?
Mars may have once had planet-wide rain and snow storms that filled lakes and rivers with liquid water, according to new research. Planetary scientists can see that riverbeds and ancient lakes litter the Martian surface, but have so far been unable to figure-out what Mars’ climate must have been like to produce them.
