EVERYDAY SCIENCE

Detailed explanation-1: -At that small size, Pluto is only about half the width of the United States. It’s about 3.6 billion miles away from the Sun, and it has a thin atmosphere composed mostly of nitrogen, methane, and carbon monoxide. On average, Pluto’s temperature is-387°F (-232°C), making it too cold to sustain life.

Detailed explanation-2: -The average temperature of Pluto’s surface is about-370 to-400 °F. It is only about 60 °F away from absolute zero, making it extremely difficult for any type of organism to live there. The main reason for these low temperatures is the dwarf planet’s distance from the Sun.

Detailed explanation-3: -At its warmest, when it is closest to the sun, Pluto can reach temperatures of minus 369 degrees Fahrenheit (minus 223 degrees Celsius). At its coolest, temperatures can fall to minus 387 degrees F (minus 233 C).

Detailed explanation-4: -Temperatures on Mercury are extreme. During the day, temperatures on the surface can reach 800 degrees Fahrenheit (430 degrees Celsius). Because the planet has no atmosphere to retain that heat, nighttime temperatures on the surface can drop to minus 290 degrees Fahrenheit (minus 180 degrees Celsius).
