Is there a black hole in Milky Way?
Today, the Milky Way galaxy possesses a supermassive black hole of 4.3 million solar masses. While this might seem tremendous, it's unusually small for a galaxy as massive as our own.
How many suns are in the Milky Way?
In our own galaxy, the Milky Way, the sun is just one of about 100 to 400 billion stars that spin around Sagittarius A*, a supermassive black hole that contains as much mass as four million suns. The deeper we look into the cosmos, the more galaxies we see.
Is Uranus the smallest planet?
To sum up, the order starts off with Mercury as the smallest planet, followed by Mars, Venus, Earth, Neptune, Uranus, Saturn and finally, Jupiter.
Is Saturn the smallest planet?
If we put our planets in 'size order' they would be listed as the following, from large to small: Jupiter, Saturn, Uranus, Neptune, Earth, Venus, Mars, and Mercury. Since we lost Pluto as an official planet, it appears that Mercury is now considered the smallest planet in the solar system.
What is Earth’s twin planet?
Venus Venus is often called "Earth's twin" because they're similar in size and structure, but Venus has extreme surface heat and a dense, toxic atmosphere.
What is the 2nd heaviest planet?
Saturn is the sixth planet from the Sun and the second-largest planet in our solar system.
Is there only 1 SUn in the universe?

Does it rain on Titan?
While Earth rain falls at about 20 miles per hour (9.2 meters per second), scientists have calculated that rain on Titan falls at about 3.5 miles per hour (1.6 meters per second), or about six times more slowly than Earth's rain. Titan's raindrops can also be pretty large.
Can humans breathe on Titan?
Titan is extremely cold, with an annual temperature of -180 C (-291 F), but thankfully, due to its thick atmosphere, humans walking outside on titan would only need warm clothing and respirators. Titan's atmosphere lacks oxygen; however it contains ice water below its surface that can be used as a source of oxygen.

On which planet does it rain 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.
