Mercury, Venus, Mars, Jupiter, and Saturn.
Mercury, Venus, (Earth), Mars, Jupiter, Saturn
Antonie van Leeuwenhoek did not invent the telescope. He is known for being one of the first microscopists, known for his work in developing and improving the microscope to observe microorganisms and cells. Galileo Galilei and Hans Lippershey are credited with the invention of the telescope.
Well there are many different ways to look at it. If you are just talking about in iur solar system there are only two planets. Mars and Jupiter. Mars is totally red, and Jupiter is yellow, red, brown and white.
Mercury, Venus, Earth and Mars are known as "inner planets" or "terrestrial planets".
The development of the telescope in the 17th century allowed astronomers to observe planets beyond those visible to the naked eye. This led to the discovery of Uranus in 1781, Neptune in 1846, and Pluto in 1930, expanding the known planets beyond the original five visible to ancient civilizations.
Mercury, Venus, (Earth), Mars, Jupiter, Saturn
Earth, Mercury, Venus, Mars, Jupiter, Saturn. There were six.
Uranus, which was discovered by Sir William HerschelPrior to the invention of the telescope, the only known planets were Mercury, Venus, Earth, Mars, Jupiter, and Saturn.Uranus was the first planet discovered by telescope.
Galileo Galilei used a telescope to make detailed observations of the stars and planets. He is most well known for suggesting that the Earth revolves around the Sun, and not the other way around.
Some sort of telescope was involved in the discovery of ALL known planets - about a thousand, at the time of this writing - with the exception of the five planets that can be seen with the naked eye.
Venus is one of the planets that is visible without a telescope. The planet has been known since antiquity. Galileo was the first astronomer to study Venus through a telescope.
Sir Issac Newton was known for being an inventor. He invented the reflective telescope and discovered some planets Uranus and Neptune also Saturn.He was physicist and astronomer, mathematician.
Yes. Mars has been known since ancient times, long before the telescope was invented.
No, Johannes Kepler is best known for describing the laws that dictate how orbits work. The Kepler planets were discovered by the Kepler telescope, a spacecraft named in his honor.
Antonie van Leeuwenhoek did not invent the telescope. He is known for being one of the first microscopists, known for his work in developing and improving the microscope to observe microorganisms and cells. Galileo Galilei and Hans Lippershey are credited with the invention of the telescope.
Lenses had been known for some time before the telescope was invented. No one really specifically "invented" the telescope lens, they simply used existing equipment (lenses) in a new device (the telescope).
Before the telescope, people were aware of the Sun, Moon, and visible planets (Mercury, Venus, Mars, Jupiter, Saturn). They were also familiar with comets and meteors as occasional celestial events. Overall, the understanding of celestial bodies was limited compared to what we know today with the aid of telescopes and advanced technology.
