# Moon size compared to earth and sun relationship

### What is the relationship between the Sun, Moon, and Earth? | Socratic

The moon is a bit more than one-fourth (27 percent) the size of Earth, told promovare-site.info, adding that the gravity of the Earth, sun and planets of. The average distance between Earth and Moon is approximately 30 The Sun happens to be times the Moon's diameter, and times as far away. poorly compared to Earth, which always has highly-reflective clouds. The sun and moon appear the same size in Earth's sky because the sun's diameter is about times greater - but the sun is also about

We begin our exploration of the Sun, which is the main source of energy for Earth's climate system, with a feeble attempt to comprehend the size scale of the Sun as compared to Earth. First, we'll look at the distance to the Sun; then we'll discuss the size of our neighborhood star as compared to our home planet.

Earth-Sun Relationship

Be prepared to feel small! Distance to the Sun The Sun is about million km 93 million miles from Earth.

This is the average distance; since Earth's orbit is an ellipsenot a perfect circle, the Earth-Sun distance varies slightly throughout the year.

In early January when the Earth is at perihelion Earth's closest point to the Sun in each orbitEarth comes within In July, when Earth reaches aphelion its furthest point from the Sunit recedes to a distance of Remember, this variation in distance is NOT the cause of our seasons on Earth. This is a misconception held by many students, so beware of this when discussing this topic with your students.

During the Apollo space program that sent astronauts to the Moon, the trip from Earth to the Moon took slightly more than two days.

## Earth, Sun and Moon

That Sun is times as far from Earth as is our Moon. At the average speed of the Apollo flights, a trip to the Sun would take more than two years. At that speed, a journey to the Sun from Earth would last more than 17 years. It could circle the Earth seven times in a single second.

### How Big Is the Moon? - The Size and Weight Compared to Earth

Nevertheless, light takes 8 minutes 19 seconds to make the trip from the Sun to Earth. This is a significant time lag, and means that we don't see changes that occur on the Sun until several minutes after they actually happen. Earth's diameter is 12, km 7, It appears quite large, but that is only because it is the closest celestial body.

The moon is a bit more than one-fourth 27 percent the size of Earth, a much smaller ratio 1: Earth's moon is the fifth largest moon in the solar system. The moon's mean radius is 1, Double those figures to get its diameter: The moon's equatorial circumference is 6, The moon's surface area is about Mass, density and gravity The moon's mass is 7.

Put another way, Earth weighs 81 times more than the moon. The moon's density is 3. That is about 60 percent of Earth's density.

The moon is the second densest moon in the solar system; Jupiter's moon Io is denser, with 3. The moon's gravitational force is only about A kilogram person would weigh lbs. A person who can jump up 10 feet on Earth would be able to jump almost 60 feet on the moon.

Like most of the solar system worlds, the moon's gravity varies based on its surface features. Super moon Because the moon's orbit is not circular, it is sometimes closer than at other times.

Perigee is the term for when the moon is closest to Earth. When a full moon coincides with perigee, we get a supermoon, which appears 14 percent larger and 30 percent brighter than usual. First applied by astrologer Richard Nolle in"supermoon" originally referred to a new or full moon that occurs when the moon is within 90 percent of its closest approach to Earth.

The astronomical term for the phenomena is perigee-syzygy moon.
