    Question 1. Why it is possible to observe a solar eclipse? Question 2. Could this be due to the identical size of the sun and moon? Question 3. How many times Sun is bigger than the moon? Question 4. How many times the Sun is farther from the Earth than the moon? Question 5. What is difference between Terrestrial Planets Outer Planets? Question 6. Can sunspot be bigger than Earth’s moon? Question 7. Can sunspot be bigger than Jupiter’s red spot? Question 8. Can sunspot be bigger than planets moons?

    Historical development of ideas about the structure of the solar system and planetary motion: Visit web page: https://en.wikipedia.org/wiki/History_of_astronomy The term “planet” comes from the Greek ἀστήρ πλανήτης meaning “wanderer” because it does not change its position against stars in the sky. In ancient planets are considered seven sites Mercury, Venus, Mars, Jupiter, Saturn, Moon and Sun This list is different in several aspects of our modern list of planets: This group lacks Earth and Uranus, Neptune have not yet found . Uranus is barely visible to the naked eye and was opened after the discovery of the telescope in 1781 by Sir William Herschel. Neptune was discovered in 1846 with the tip of the pen due to gravitational disturbances that turns the motion of Uranus by Johann Galle of the position predicted by Urbain Le Verrier. Classification of the planets The planets of the Solar system revolve around the Sun in elliptical orbits (Kepler’s low) and are divided into two groups. The planets that are closer to the Sun than the Earth , are called inferior planets. This is Mercury and Venus. The planets that are farther from the Sun than the Earth , called the superior planets. This Mars, Jupiter , Saturn, Uranus and Neptune. The planets inside the orbit of the earth are called the Inferior Planets: Mercury and Venus. The planets outside the orbit of the earth are called the Superior Planets: Mars, Jupiter, Saturn, Uranus, Neptune, and Pluto. The planets inside the asteroid belt are termed the Inner Planets (or the Terrestrial Planets): Mercury, Venus, Earth, and Mars. The planets outside the asteroid belt are termed the Outer Planets: Jupiter, Saturn, Uranus, Neptune, and Pluto. The planets sharing the gaseous structure of Jupiter are termed the Gas Giant (or Jovian) Planets: Jupiter, Saturn, Uranus, and Neptune.

    1. Learn about structure of Solar System. 2. Measuring size of the Sun and Moon using of software SalsaJ. 3. Measuring sunspot’s diameter using the SalsaJ software and will compare the objects of the Solar system using the same software and will made diagram to compare the dimention of the objects. 4. Searching information at Internet. 5. Explanation of how to use SalsaJ for measurement of dimensions: SalsaJ is open source software. You can download it from: http://www.euhou.net/index.php/salsaj-software-mainmenu-9 Look at my presentations how to make measurement of dimensions: http://astronomy-uktc.blogspot.com/2014/12/what-is-salsaj.html http://astronomy-uktc.blogspot.com/2014/12/measuring-sunspots-diameter-using.html
