Question:

Boojho made the following sketch of the solar system. Is the sketch correct? If not correct it.

Answer:

Planets of the solar system in sequence of their distances from the sun are: Mercury. Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune. Therefore, Boojho's sketch of the solar system is not correct because he has interchanged the positions of Mars and Venus and also the positions of Uranus and Neptune. Also, he has shown the Asteroid belt in the gap between the orbits of Jupiter and Saturn. This is not correct. The asteroid belt is located between the orbits of Mars and Jupiter. The correct sketch of the solar system is shown in the given figure.
