Extra-close oppositions of Mars happen every 15 to 17 years, when we pass between Mars and the Sun around the time of its perihelion (closest point to the Sun in orbit). The minimum distance between Earth and Mars has been declining over the years, and in 2003 the minimum distance was 55.76 million km, nearer than any such encounter in almost ...
The closest in the past 1,000 years was in 1761, when Mars and Jupiter appeared to the naked eye as a single bright object, according to Giorgini. Looking ahead, the year 2348 will be almost as close.
Because the orbit of Mars is eccentric, the magnitude at opposition from the Sun can range from about −3.0 to −1.4. [195] The minimum brightness is magnitude +1.86 when the planet is near aphelion and in conjunction with the Sun. [19] At its brightest, Mars (along with Jupiter) is second only to Venus in apparent brightness. [19]
The biggest planet in the solar system will be on display in the December sky as it shines brighter than it has all year. On Saturday, Dec. 7, Jupiter will reach opposition, the point in its orbit ...

Juno is the second spacecraft to orbit Jupiter, after the nuclear powered Galileo orbiter, which orbited from 1995 to 2003. [8] Unlike all earlier spacecraft sent to the outer planets, [ 8 ] Juno is powered by solar panels , commonly used by satellites orbiting Earth and working in the inner Solar System , whereas radioisotope thermoelectric ...
It is 55 m (180 ft)-long, 9 m (30 ft)-diameter at its widest point, and is capable of transporting up to 100 tonnes (220,000 lb) of cargo and passengers per trip to Mars, with on-orbit propellant refill before the interplanetary part of the journey.
Just one day before opposition, Jupiter will be around 367 million miles away from the Earth, the closest the two planets have been in 59 years, according to NASA. The last time that Jupiter was ...
