The video discusses various planets in our universe, both within and outside our solar system, that have unique and often frightening features. These include "zombie worlds" orbiting a pulsar, a planet with extremely strong winds that can cause death by "molten glass rain," and a planet that rains molten iron. The video also mentions planets that are extremely hot, such as Kepler-70b, which has a surface temperature of almost 7,000 degrees Celsius.
The video also touches on planets in our own solar system, including Jupiter, which has a massive storm that has been raging for 340 years, and Venus, which has a thick, toxic atmosphere that can cause death by burning, crushing, and asphyxiation.
Finally, the video mentions "Planet X," a hypothetical planet in our solar system that has not been directly observed but is believed to exist based on mathematical models. The video ends by noting that the most unique, dangerous, and deadly planet in the universe is actually Earth, where humans can die in a variety of ways due to conflicts, diseases, and other factors.

3. The nearest Earth-like planet is only 12 light years away from us.
4. Planets are formed when dense disks of gas and dust start encircling young stars.
5. The process of accretion forms a brand new planet with its own peculiarities and features.
6. Some exoplanets have features similar to those in our own solar system, while others are strange and unknown.
7. There are exoplanets that are considered "zombie worlds" due to their uninhabitable environments.
8. The star PSR B1257+12 is a pulsar that constantly leaks electromagnetic radiation.
9. The exoplanets orbiting PSR B1257+12 are saturated with radiation, making them uninhabitable.

12. Jupiter has dozens of ways to kill you, including its lack of oxygen, extreme pressure, and high temperature.
13. Venus has a thick atmosphere that is poisonous and hot, making it inhospitable to life.
14. The planet Methuselah, also known as PSR B1620-26b, is 13 billion years old and orbits two burned-out stars.
