Has planet 9 Been Found?
As of August 2021,
no observation of Planet Nine had been announced

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)
What would planet 9 be called?
20, 2016. The alleged “Planet Nine,” also called “
Planet X
,” is believed to be about 10 times the mass of Earth and 5,000 times the mass of Pluto.
Which planet can support life?
Nonetheless,
Earth
is the only place in the Universe known to harbor life.
Is there a 10th planet?
Astronomers have found a
tenth planet
, larger than Pluto and nearly three times farther from the Sun as Pluto is today. Temporarily designated 2003 UB313, the new planet is the most distant object yet seen in the solar system, 97 times farther from the Sun than the Earth is.

Will a black hole come to earth?
Absolutely not
. While a black hole does have an immense gravitational field, they are only “dangerous” if you get very close to them. … It would get very dark of course and very cold, but the black hole’s gravity at our distance from it would not be a concern. Is there life on other planets?
