Exploring our planets...a fun journey to space!
MERCURY
SIZE - It is about the size of our Moon; a little over quarter the size of earth measuring only 38% of earth's size.
TEMPERATURE - Mercury's temperatures can go between -279 Fahrenheit (-173 Celsius) at night to 801 Fahrenheit (427 Celsius) during the day

VENUS
SIZE - It is about the size of our Moon; a little over quarter the size of earth measuring only 38% of earth's size.
TEMPERATURE - The average temperature on Venus is 864 degrees Fahrenheit (462 degrees Celsius)

CHARACTERISTICS OF THE PLANETS
EARTH
SIZE - The circumference of Earth at the equator is about 24,902 miles (40,075 km), but from pole-to-pole — the meridional circumference — Earth is only 24,860 miles (40,008 km) around
TEMPERATURE - The average temperature on Earth is about 61 degrees F (16 C). But temperatures vary greatly around the world depending on the time of year, ocean and wind currents and weather conditions

MARS
SIZE - Mars has a diameter of 4,222 miles (6,794 km), but from pole to pole, the diameter is 4,196 miles (6,752 km)
TEMPERATURE - In winter, near the poles temperatures can get down to minus 195 degrees F (minus 125 degrees C). A summer day on Mars may get up to 70 degrees F (20 degrees C) near the equator

JUPITER
SIZE - Jupiter has a mean radius of 43,440.7 miles (69,911 kilometers), about a tenth that of the sun. However, its rapid rotation — it spins once every 9.8 hours — causes it to bulge at the equator, where the diameter is 88,846 miles (142,984 km)
TEMPERATURE - With an average temperature of minus 234 degrees Fahrenheit (minus 145 degrees Celsius), Jupiter is frigid even in its warmest weather

SATURN
SIZE - Saturn is the second largest planet in the solar system. The mean radius of the body of Saturn is 36,184 miles (58,232 kilometers)
TEMPERATURE - With an average temperature of minus 288 degrees Fahrenheit (minus178 degrees Celsius), Saturn is a pretty cool planet

URANUS
SIZE - Uranus is the smallest of the gas giants in the outer solar system. The surface area of Uranus is 8.1×109 km2
TEMPERATURE - Uranus hits the coldest temperatures of any planet: With minimum atmospheric temperature of -224°CUranus is nearly coldest planet in the solar system

NEPTUNE
SIZE - Neptune is the third most massive. Despite its great size. The diameter of Neptune is 49,500 km
TEMPERATURE - At its surface, where the clouds of the planet touch space, the temperature of Neptune can dip down to55 Kelvin. That's -218 degrees Celsius. The average temperature of Neptune is 73 K (-200 Celsius). But one strange anomaly is the planet's south pole, which is 10 degrees warmer than the rest of planet
