How does NASA help our understanding of the Solar System?
NASA’s robotic explorers gather data to help scientists understand how the planets formed, what triggered different evolutionary paths among planets, what processes have occurred and are active, and how Earth among the planets became habitable.
What invention added to our current understanding of the Solar System and Earth?
When Galileo Galilei pointed a new invention called the telescope at Jupiter, he made a startling discovery. The planet had four “stars” surrounding it.
How did scientists learn about Earth’s place in the Solar System?
Telescopes use lenses and mirrors to see beyond Earth’s borders. Scientists learned quite a bit with telescopes. This paved the way for more space exploration. Humans have taken trips to the Moon and dozens of space shuttle flights.
Who explored the solar system?
Galileo was the first to discover physical details about the individual bodies of the Solar System. He discovered that the Moon was cratered, that the Sun was marked with sunspots, and that Jupiter had four satellites in orbit around it.
Who proved the modern solar system model?
Nicholas Copernicus
Copernicus’s Heliocentric Model During the 16th century, Nicholas Copernicus introduced a new model which was consistent with the observations and allowed for perfect circular motion.
Who investigated the Solar System?
How many planets in the Solar System have no moons?
Of the terrestrial (rocky) planets of the inner solar system, neither Mercury nor Venus have any moons at all, Earth has one and Mars has its two small moons….Read More.

What is the most accepted theory about the origin of the Solar System?
Contemporary view The most widely accepted hypothesis of planetary formation is known as the nebular hypothesis. This hypothesis posits that, 4.6 billion years ago, the Solar System was formed by the gravitational collapse of a giant molecular cloud spanning several light-years.
Will humans ever go back to the Moon?
Humanity hasn’t been back to Earth’s nearest neighbor since (though many of our robotic probes have). NASA has mounted multiple crewed moon projects since Apollo, including the ambitious Constellation Program in the mid-2000s, but none of them have gone the distance. So what was different about Apollo?
Why does the Moon have less volatile substances than the Earth?
Answer: Moon rocks contain few volatile substances (e.g. water), which implies extra baking of the lunar surface relative to that of Earth. The relative abundance of oxygen isotopes on Earth and on the Moon are identical, which suggests that the Earth and Moon formed at the same distance from the Sun.
Is there a natural explanation for the Moon?
Also, this hypothesis does not have a natural explanation for the extra baking the lunar material has received. The Capture Theory: This theory proposes that the Moon was formed somewhere else in the solar system, and was later captured by the gravitational field of the Earth.
What is the giant impact theory of the Moon?
More About The Giant Impactor Theory. In the mid-1970s, scientists proposed the giant impact scenario for the formation of the Moon. The idea was that an off-center impact of a roughly Mars-sized body with a young Earth could provide Earth with its fast initial spin, and eject enough debris into orbit to form the Moon.
