Mithos raises his hand "The Earth is the 3rd planet in distance from the sun, and the 5th largest in diametre." |
Serena raised her hand. Earth is the third planet in distance from the sun, and the fifth largest in diametre. |
Evy raised her hand, but was too slow to answer. |

Now, the Earth and the moon move around the sun on a slightly elliptical orbit, meaning it is not a perfect circle, but a slight oval. How long is the earth's orbit? How far does it travel around the sun? |
Nat raises her hand. "I agree with Mithos and Serena's anwsers: the earth is the third planet from the sun and the fifth largest in diameter." |
Amy raised her hand. "The Earth takes 365 and a fourth days to revolve around the Sun, which is our year, also explaining leaps years with 366 days every four years," Amy answered. |
Amy raised her hand again. "Just a fun fact - the distance of Earth's revolution is 942,000,000 kilometers," she added. |
"The earth's approximate orbit is 938,900,000 km. or 583,400,000 mi. long," Nat anwsers again. "But I do not know the distance it travels around the sun." |
Mithos raises his hand "The Earth's orbit is 365 days and it travels 595 million miles from the sun." |
Earth's average distance from the sun is 149,597,870 km. |
Mithos raised his hand yet again "Oh sorry Professor then than would be 93 million miles or 149,600,000 km" |
*raise her hand* I have that the Semi-major axis is 149,597,887 km(1.000 000 11 AU). The Peripelion is 147,098,074 km (0.983 289 9 AU). The Aphlion is 152,097,701 km (1.016 710 3 AU) |

Does anyone know ho fast we travel through space? |
"My mistake! The distance of the earth from the sun is 149,503,000 km or 92,897,000 mi. The earth's orbit is aproximately 938,900,000 km or 583,400,000 mi." |
Earth's speed is 18.55 miles per second. |
Or 30 km/sec. |
"The earth travels at a speed of about 106,000 km/h or about 66,000 mph along its orbit." |
Mithos raised his hand "That would be 107,300 km/h or 67,062 miles per hour" |
The Average Orbital Speed is 29.783 km per second. The Max. Orbital speed is 30.287 km/s and the Min. Orbital Speed is 29.291 km/s |

Anyways, The earth rotates on its axis once every 23hrs 56mins and 4.1sec, not an exact 24hrs. A point on the equator therefore rotates at a rate of a little more than 1600 km/h (about 1000 mph), and a point on the earth at the latitude of Portland, Oregon (45° north), rotates at about 1073 km/h (about 667 mph). Now composition. The earth is made up of 5 parts or layers, starting with the atmosphere. What are the other 4? |
Evy raised her hand. "30 km/sec or 1800km/m or 108 000 km/h. Is that right?" |
1669 km per hour or 67,000 miles per hour. |
The Crust The Mantle The Outer Core The Inner Core |
raises hand. "The crust, upper mantle, lower mantle, the inner core and the outer core...?" |
