SOHO satellite & Sun

SOHO and the Sun. Computer illustration of the Solar and Heliospheric Observatory (SOHO, upper right) and several solar phenomena it studies. SOHO was launched on 2nd December 1995 by the European Space Agency (ESA) for the International Solar Terrestrial Physics (ISTP) program. The solar features seen here include the Sun's magnetic field (blue, top right), electromagnetic radiation (spectrum, top centre), sunspots (dark, lower centre), the solar wind (arrows, lower left) and solar flares (bottom left). SOHO monitors solar activity continuously, as periods of high activity can have adverse effects on Earth

Solar system orbits

Planetary orbits. Computer illustration of the orbits of some of the planets of the solar system. The Sun is at centre. The orbit of Pluto (outermost) is highly elliptical and is inclined compared to the orbits of the inner planets. The orbits of Mars, Earth, Venus and Mercury, the planets nearest the Sun, are all within the inner circle at this scale. Pluto's orbit overlaps with that of Neptune, meaning that Neptune is the furthest planet from the Sun at times. Inside Neptune's orbit, in order of their decreasing distance from the Sun, are the orbits of Uranus, Saturn and Jupiter
