Read the text, look at the table and do the math

Light travels in a vacuum \(\approx 299,792\) km per second (to ease the recording, this distance is rounded up to \(300,000\) km per second). During this time, light can circle the Earth along the equator as much as \(7.5\) times! This distance seems incredibly large for humans, but for the cosmos it is, of course, very small.What distance will light cover in a minute of its travel through the vacuum? To do this, multiply \(300,000\) km by \(60\) seconds and the answer will be \(18,000,000\) km. Similarly, astrophysicists introduced the concept of a "light year", determining how much distance light travels in a vacuum in \(12\) months.

When completing the task, you will need this table:

Distances between some space objects in kilometers

	Sun
Earth	\(\approx 150\) million
Mars	\(\approx 228\) million
Jupiter	\(\approx 779\) million
Neptune	\( \approx 4.5\) billion

Calculate how long it will take for the light produced by one of the luminous objects to reach the other one.

• \(8\) minutes \(20\) seconds
• \(4\) minutes \(20\) seconds
• \(4\) hours \(10\) minutes
• \(35\) minutes
• \(7\) minutes \(50\) seconds
• \(4\) minutes \(40\) seconds
• \(4\) hours \(40\) minutes
• \(40\) minutes

1. The light emitted by the Sun reaches the Earth in about [ ].
2. The light emitted by your desk lamp in the evening when turned on will reach Mars (if both planets are on the same side of the Sun) in [ ].
3. The light emitted by the Sun will take [ ] to reach the last planet in the solar system — Neptune.
4. The largest atmospheric vortex in the solar system is the Great Red Spot on Jupiter, which can be seen with a telescope, but the light transmitting the image will reach the Earth in almost [ ].
