The planet is at minimum and maximum distances when it is at either end of the major axis. In this case the major axis is 0.5 AU so the semimajor axis is 0.25 AU. The eccentricity is found by noting that the Sun is 0.15 AU displaced from the centre, so the eccentricity is 0.15/0.25 or 0.6.
The semiminor axis is equal to the semimajor axis times sqrt(1 - e-squared) which in this case is equal to 0.2.

If comet Halley's major axis was scaled down to 15 cm how far apart would the foci be?
They would be roughly 14.49 cm apart, given a major axis of 35.6 AU, and perihelion of about .58720 AU. I am assuming that distances from the foci at perihelion and aphelion will be equal or very close to equal. The major axis minus twice the distance at perihelion gives a distance of about 34.426 AU between foci. 35.6 AU is to 15 cm as 34.4 AU is to x cm. This gives about 14.49 cm as the proportional distance between foci with the major axis scaled down to 15 cm.
How far is planet nibiru from the earth?
In Babylonian Astronomy Nibiru refers to Jupiter, which is 778,547,200 km away from the sun at it's (semi-major axis) average distance. At any given time the Earth and Jupiter can be a various distances from each other depending on how far from the sun they are and at what alignment to each other they are: Earth's Aphelion distance plus Jupiter's Aphelion distance at opposition (152,097,701 + 816,520,800 ) is 968,618,501 km. Earth's Aphelion distance minus Jupiter's Perihelion distance at conjunction (152,097,701 - 740,573,600) is 588,475,899 km. An endless number of alignments and distances are possible but these are the farthest and closest possible distances.
How far in astronomical units is Ceres from the sun?
The dwarf planet Ceres is about 2.8 astronomical units away from the Sun.
What is Venus's distance from Mercury in kilometers?
Aphelion (Furthest distance) 69,816,900 km - 43382210 miles - 0.466697AU Perihelion (Closest Distance) 46,001,200 km - 28583820 miles - 0.307499 AU Semi Major Axis (Mean) 57,909,100 km - 35983046 miles - 0.387098 AU
Which planet is 227 940 000 kilometers from the sun?
Mars has a semi major axis of 227,939,100 km from the Sun. But this is only an average and will only be at this distance from the Sun twice in it's orbit. At Aphelion (Furthest) is will be 249,209,300 km from the Sun, whereas at Perihelion (Closest) it will be 206,669,000 km.
What is the name of the point in space where an object is closest to the sun?
That is perihelion. Furthest away is aphelion, pronounced ap-helion. For each planet, perihelion and aphelion are at opposite ends of the major axis of the elliptical orbit.

Can you consider that the planets in your solar system as having elliptical orbits with the same major axis and the perihelion and aphelion on the same side on this axis?
NO. jus...just no. Although I did see an alien with a sharpie in his pooper once.
What is an object at a distance of 68 AU from the Earth?
All objects orbiting the Sun do so in an elliptical orbit. Therefore sometimes they are further away while at others they are closer.To be 68 AU from the Earth you would need to know the position of the Earth relative to the said object as the Earth could be on the other side of the Sun.The closest objects to 68 AU from the Sun would be Eris or 2007 OR10.Eris: Aphelion 97.56 AU Perihelion 37.77 AU Semi major axis (Average) 67.67 AU2007 OR10: Aphelion 100.79 AU Perihelion 33.62 AU Semi major axis (Average) 67.21 AU
The distance from the earth to the sun is called?
The average distance of a planet to the sun is the Semi-major axis. The furthest it gets is the Aphelion and the closest it gets is its Perihelion. The Sun to Earth Distance is also known as one Astronomical Unit (AU).
What is 740573600-778547200-816520800 in words?
The numbers represent the perihelion, aphelion and the semi-major axis of planet Jupiter. In other words, the first number is the point in orbit closest to the Sun. The last number is the point in orbit farthest from the Sun. The middle number represents the distance from the center of the Jupiter's elliptical orbit, to one of the long sides of the ellipse.
What is the effect the perihelion and aphelion have on earths seasons?
The aphelion has many interesting effects on the earth. For one, the orbital velocity of the Earth slows down as it reaches its aphelion. It also has an effect on the climate. Due to the point in its orbit the Earth climate is made cooler and warmer in the Northern and Summer Hemisphere creating milder or more severe seasons. Some scientist hypothesize that major climate shifts like the Ice Ages are caused in part by major shifts in the Earth's Orbit which can alter its apsis points.At aphelion, Earth receives 6.9% less of the solar radiation than at perihelion. Aphelion happens around July 4, so this means slightly cooler summers for the Northern Hemisphere and slightly cooler winter for the Southern Hemisphere..Perihelion is the closest point to the sun in a planet's orbit. Perihelion is one of the two points of apsis on elliptical orbit. The closest point is generally called an periapsis and the farthest point apoapsis. This changes depending on the object being orbited. For orbiting satellites around theEarth, these two points are called the perigee and and the apogee. For other object the suffix changes to match that object being orbited.These are the points in the earth's orbit at which it is closest to,and farthest from, the sun, respectively.
