Do the planets have same distance from the sun?
Build background about the astronomical unit (AU). It is a unit of length equal to the average distance from Earth to sun, approximately 149,600,000 kilometers (92,957,000 miles). Planets farther away would have AU greater than 1; planets closer would have AU less than 1.
Are all the planets the same distance apart?
The distances between planets will vary depending on where each planet is in its orbit around the Sun. Sometimes the distances will be closer and other times they will be farther away. The reason for this is that the planets have elliptical orbits and none of them are perfect circles.
Why does the distance between a given planet and the sun varies?
The distance to the Sun changes because Earth’s orbit is an ellipse — like a slightly stretched-out circle. In fact, all the planets follow elliptical orbits. But the “stretching” varies from planet to planet. Venus has the most nearly circular orbit, so Venus’s distance from the Sun varies by less than one percent.
Which planet is 1.78 billion miles from the sun?
Uranus
Uranus is located an average of nearly 1.78 billion miles from the sun.At its closest point, Earth and Uranus are more than 1.6 miles apart. At their farthest, the two planets are more than 1.8 billion miles apart.
How many Earths can fit in the moon?
Size and Distance The Moon is an average of 238,855 miles (384,400 kilometers) away. That means 30 Earth-sized planets could fit in between Earth and the Moon.
Which planet has 16 hours in a day?
Neptune
Not long after Neptune completed its first orbit around the sun since its discovery in 1846, scientists have managed to calculate the exact length of one day on the distant gas giant planet.
Which planet is closest to the sun?
Mercury
Mercury is the planet closest to the sun. In 2004, NASA launched its MErcury Surface, Space ENvironment, GEochemistry, and Ranging mission, nicknamed MESSENGER.
Which planet has a life?
Understanding planetary habitability is partly an extrapolation of the conditions on Earth, as this is the only planet known to support life.
Can humans live on any other planet?
We may well have people living on the Moon. We may have people living on the moons of Jupiter and other planets. We may have people making habitats on asteroids … Richard Gott has estimated that the human race could survive for another 7.8 million years, but it is not likely to ever colonize other planets.
