Jupiter/Apparent magnitude (V)

What is the magnitude of Jupiter as seen from the Earth?

Depending on Jupiter’s position with respect to the Earth, it can vary in visual magnitude from as bright as −2.94 at opposition down to −1.66 during conjunction with the Sun. The mean apparent magnitude is −2.20 with a standard deviation of 0.33.

Why do you think two stars with the same magnitude might have different absolute magnitudes?

Extinction (the absorption or scattering of light) also affects apparent magnitude by making a star appear dimmer. Yes the two can have same absolute intensity and different relative magnitudes and vice versa. As the light travels it spreads, and hence the intensity of light reaching the earth lessens.

How do you compare apparent magnitude?

A star with apparent magnitude +3 was 8 (2x2x2) times brighter than a star with apparent magnitude +6….Comparing the magnitudes of different objects.

Apparent magnitude difference (m2 – m1)	Ratio of apparent brightness (b1/b2)
2	(2.512)2 = 6.31
3	(2.512)3 = 15.85
4	(2.512)4 = 39.82
5	(2.512)5 = 100

What is the difference between apparent magnitude and absolute magnitude?

Astronomers define star brightness in terms of apparent magnitude — how bright the star appears from Earth — and absolute magnitude — how bright the star appears at a standard distance of 32.6 light-years, or 10 parsecs.

Which of the following planets never reaches opposition as seen from the Earth?

Consider that Venus and Mercury can never be at opposition as seen from Earth. Their orbits are closer to the sun than Earth’s, so they can never appear opposite the sun in our sky.

What is the relationship between apparent magnitude and absolute magnitude?

Is apparent magnitude the same as apparent brightness?

Apparent Magnitude and Apparent Brightness are the same terms – they refer to the same concept. An unaided human eye can only see objects having an Apparent Brightness of up to 6. Any star with a higher magnitude is not visible to the unaided human eye. Luminosity is the opposite of the two.

Are apparent magnitude and absolute magnitude the same?

What is the difference between absolute magnitude and apparent magnitude which is a more accurate measure of how bright a star really is and why?

Astronomers determine the brightness of stars in terms of absolute and apparent magnitude scales. Apparent magnitude measures the brightness of the star observed from any point, whereas absolute magnitude measures the brightness of the star observed from a standard distance away, which is 32.58 light years.

Can you see Jupiter and its satellites from Mars?

At the time, Io was behind Jupiter as seen from Mars, and Jupiter’s giant red spot had rotated out of view. This image has been specially processed to show both Jupiter and its satellites, since Jupiter, at an apparent magnitude of -1.8, was much brighter than the three satellites. Jupiter and Galilean Satellites.

What is the magnitude of the peak of Mars?

The planet peaks near magnitude –3 (–2.94 to be exact) at favorable oppositions, when Mars is particularly close to Earth. The phase functions of the giant planets are similar to one another.

Is Mars brighter than we thought?

On the whole, Mars turned out to be somewhat brighter than previously thought. The planet peaks near magnitude –3 (–2.94 to be exact) at favorable oppositions, when Mars is particularly close to Earth. The phase functions of the giant planets are similar to one another.

What is the brightness of Jupiter Saturn and Mercury?

Jupiter & Saturn. By coincidence, Jupiter also peaks at magnitude –2.94, so it ties with Mars for second place in brightness as seen from the Earth. Mercury at its brightest is about a half-magnitude fainter at –2.48, and Saturn takes fifth place. Saturn’s brightest magnitude, –0.55, occurs when the planet is both at perihelion
