Explanation: So the distance between the earth and the sun is 150 million kilometers. In scientific notation, you have to find the number between 1 and 10, then multiply it by 10x. So the number between 1 and 10 in 150,000,000 is 1.5, and a number of decimal points is 8. So the answer is 1.5 ⋅ 108.
From this, they deduced the distance Earth-Mars. Then, using the Kepler law $$\frac{a^3}{p^2}= constant$$ (where $a$ is the distance between the planet and the Sun, and $p$ the sideral time) they could figure out what was the distance to the Sun.

(An astronomical unit is the distance from Earth to the Sun, or about 150 million km.) During the first six years of its operation, the Hubble Space Telescope circled Earth 37,000 times, for a total of 1,280,000,000 km. Use scientific notation to find the number of km in one orbit.
As an example, the distance from Earth to the Sun is about 150,000,000,000 meters—a very large distance indeed. In scientific notation, the distance is written as \(1.5 \times 10^{11} \: \text{m}\).
The average distance between the Earth and the Sun is 92,955,807 miles (149,597,870 km). Most people just round it up to 93 million miles. This distance is called an astronomical unit or AU and is used to measure and compare other distances in space.
astronomical unit (AU, or au), a unit of length effectively equal to the average, or mean, distance between Earth and the Sun, defined as 149,597,870.7 km (92,955,807.3 miles).
The smaller the solar parallax, the greater the distance between the Sun and Earth: a solar parallax of 15″ is equivalent to an Earth–Sun distance of 13,750 Earth radii.

You are probably already familiar with this notation. Any number can be written as a number between 1.00 and 9.99... multiplied by 10 raised to a power. Here are a few examples: The distance from Los Angeles to New York is about. 4 550 km = 4.55 x 10 3 km. The distance from Earth to our moon is.
