When? Mars and Earth are constantly moving, so the distance between them is constantly changing. If you're really interested, it would be trivial to look up their relative distances from the sun, and figure out how far apart they can ever be (if they're both on opposite sides of the sun) or how close they can ever get (if they're both on the same side of the sun).
I'm not going to do that for you, though, because I would hate to spoil your joy of discovery.

The above is not in scientific notation. It also suggests that the distance is a constant whereas it varies greatly depending on their relative positions in their orbit.
The nearest distance (perigee) is 5.6*1010 metres or 5.6*107 kilometres.
The greatest distance (apogee) is 4.0*1011 metres or 4.0*108 kilometres.
The average distance is 2.25*1011 metres or 2.25*108 kilometres.
Mars does not have scientific notation. Various measures concerning Mars: its distance from the sun or earth, its mass, radius, length of orbit may be expressed in scientific notation but any of those is a characteristic of Mars in scientific notation, not Mars itself. Besides, you have not specified which characteristic.
The distance between these orbits is 249,209,300.0 km. In scientific notation, it's 2.49209300 x 108 km. Move 8 decimal places to the left to get that number in that notation!
The radius is approximately 3.4*106 metres.
The average distance from Jupiter to the Sun is 7.8*10^8 kilometres.
4th planet from the sun
About 2.28 x 108 kilometers, on average.
4.838 x 10^8 miles
1.416 x 10^8 miles
It is: 1.277*10^6 in scientific notation
Mercury has a radius of 2439.5km. In scientific notation, this would be 2.4x103km.
I believe you mean scientific notation. 0.0000547 in scientific notation is 5.47 x 10-5.
100 million in Scientific Notation = 1 x 108
An exact quantity of people used for a comparison. Their is also scientific notation to standard notation which is changing scientific notation so it would be a standard number.

It's mass is 6.4185×1023 kg. If you want it in standard notation, it's 618,500,000,000,000,000,000 kg
It depends on the way in which it is written!
o.ooo1 (Influenza Virus)
Really small. 3.68x10^37% in scientific notation.
It's not necessary to put numbers of this size into scientific notation but if you really have to, go with 4.125 x 10^0
It's not necessary to put numbers of this size into scientific notation but if you really have to, go with 4.215 x 10^0
Planet Mars has a mass of 639 x 1021 kilograms (639,000,000,000,000,000,000,000kg)
A proton is 2x10^-14m, or 0.00000000000002m
Proxima Centauri is a star and there is no scientific notation for a star. There will be scientific notations for the values of its distance, its size, its age, luminosity, magnitude and so on but the question is not about any of them!
