      well the size you can simply measure in a telescope once given the distance from earth. and once they know how big it is they can multiply the suns substance (IDK what it is) times the volume to get the mass. and temperature they can see using thermal imaging. Subsequent transit observations in the 19th century were to further refine this measurement. When Newcomb combined the 18th century data with those from the / Venus transits, he derived a refined solar distance of ± million kilometers (a precision of 1 part in ).

      FE theory asserts that the distance of the Sun is miles (above the flat Earth surface). This it is said can be accounted for by the fact that on 21st March the Sun is directly overhead as seen from the equator and at 45 deg altitude as seen from either 45 deg N or S latitude. The distance from the center of our Galaxy to the Sun is ab light years (a light year is about 6 trillion miles), which is approximately halfway out on one of the Milky Way's curving arms. The Sun and its planets take a period of million years to revolve around the galactic center.

      Well the first one i.e. the radius of the Sun is pretty easy to find. Know the diameter of the Sun and half it or know the circumference of The Sun and apply.   The Suns distance is well known to science now and has been measured to a high degree of accuracy. To so suddenly to make a claim that the Suns distance is only miles away without a very good explanation as to why you think that is unjustified.

Measurement of the sun"s distance by John Harris Download PDF EPUB FB2

ISBN: OCLC Number: Notes: Half title: Lecture fifth. Reproduction of original in: D.B. Weldon Library, University of Western Ontario. First, you must know that Earth orbits the sun at a distance of approximately million km. Light moves atkm per second.

When one divides these numbers, the result is seconds. That. Additional Physical Format: Print version: Harris, John. Measurement of the sun's distance. London: N. Trübner, (OCoLC) Material Type. The calculations reveal that the distance from Venus to the Sun is about 72% of the distance from Earth to the Sun.

Additionally, inastronomers used a rare and informative event to finalize the calculations—a transit of Venus in front of the Sun. The calculation at the time was only 2% from our modern figures. While holding the pinhole viewer steady, measure the size of the Sun’s image on the piece of paper in centimeters.

Record this measurement below. The equation on the right is used to calculate the Sun’s diameter. Using sun image size (d) and the string length (l) you recorded above, along with the distance from the Sun to Earth (L), calculateFile Size: KB. On the Sizes and Distances (of the Sun and Moon) (Περὶ μεγεθῶν καὶ ἀποστημάτων [ἡλίου καὶ σελήνης], Peri megethon kai apostematon) is widely accepted as the only extant work written by Aristarchus of Samos, an ancient Greek astronomer who lived circa – work calculates the sizes of the Sun and Moon, as well as their distances from.

Under the new definition, the astronomical unit (or AU) — the measurement used for the Earth-sun distance — is no longer always in flux, depending on the length of a day and other changing.

The Earths orbital distance from the sun is ,km (92, miles) on average, enough to fit more suns between the suns surface and Earth. Eratosthenes of Cyrene (/ ɛr ə ˈ t ɒ s θ ə n iː z /; Greek: Ἐρατοσθένης ὁ Κυρηναῖος, romanized: Eratosthénēs ho Kurēnaĩos, IPA: [eratostʰénɛːs]; c.

BC – c. / BC) was a Greek polymath: a mathematician, geographer, poet, astronomer, and music was a man of learning, becoming the chief librarian at the Library of : BC, Cyrene.

The first distance to be measured with any accuracy was that of the Moon. In the middle of the 2nd century BCE, Greek astronomer Hipparchus pioneered the use of a method known as idea. Using available coordinates and Angles and some basic Geometry, it's easy to get a general distance to the Sun. The measurement is based on the speed of light, a fixed distance that has nothing to do with the sun's mass.

A meter is defined as the distance traveled by. The book The Transits of Venus, by Sheehan and Westfall, describes how Aristarchus used Hipparchus' calculation of the Earth-Moon distance, who in turn used Eratosthenes' calculation of the Earth's circumference, to calculate the Earth-Sun distance.

Aristarchus of Samos was the first to seriously calculate the distance to the Sun, using geometry. When the Moon is exactly half illuminated when. This is a book on how to measure length and distance.

You technically could then calculate volume using that distance, but the book sticks to just the basic measurement of length. The book is nothing fancy or complicated. It has color photos and shows various things that you can measure (like length of guinea pig or depth of a swimming pool)/5(2).

He realized that we could figure out the distance to the sun relative to the distance to the moon. He noted that the sun, moon, and earth form a right triangle (right.

On the topic "Using radar to measure the distance to the Sun": Radar measurements of the distances to the moon, Mercury, Venus and Mars have been made but, as far as I know, there has been no direct radar measurements of the distance to the sun using radar.

Distance Between Sun and Earth Mentioned in Hanuman Chalisa: According to Records, For the first time inJean Richer and Giovanni Domenico Cassini measured the distance between Earth and Sun as 22, times of Earth Radii.

With the distance to the Moon known, the stage was set for another Greek astronomer, Aristarchus, to take the first stab at determining the Earth's Author: Morgan Rehnberg.

If D is the distance between the north pole and the projected orbit of the sun on the flat earth, then at equinox the ratio between the distance from a vantage point at the equator observing the sunset to a vantage point at the north pole in the same instant is (SQRT (D^2+D^2))/D = 1, The standard unit of measurement for the distance from the sun to the earth is one Astronomical Unit (AU).

An AU, as defined by the International Astronomical Union, is aboutkm. Eratosthenes used his measurement of the size of the earth, and previous measurments of the moon, and determined the distance to the sun to bestadia. Assuming one stadia is to meters, this yields an answer of to million km (accurate within 2%).The distance of each planet from the sun is a determinant of its basic composition.

Mars and the planets inside its orbit are known as terrestrial planets because they are composed mostly of rock. The ones outside its orbits are known as gas giants or, in the case of the two outermost planets, ice giants. THE distance of the sun from the earth or, speaking more correctly—for the distance is, of course, variable—the semi-major axis of the earth's orbit, is the most important constant in by: 1.
