Venus and Saturn will be in conjunction with each other on June 30-July 1, a full moon night.

"The Celestial show begins on Saturday evening. When the sun is about to set, Venus will appear first , a bright point of light not far above the horizon and as the sky darkens, one will also be able to spot Saturn. The two planets will almost touch each other" - Ajay Talwar of Delhi's Amateur Astronomer Association.

Earth at Aphelion on July 7
On July 7 at 12 noon, the Earth is at its furthest point from the Sun (aphelion), on its year-long slightly elliptical orbit around the Sun.
The distance at that time is 152,097,040 km, which is about 5 million km further away than its closest point in early January.

Because of this change in distance, the whole Earth receives about 8% less energy from the Sun than it does in early January. The Earth is now also orbiting at its slowest velocity around the Sun - Brian Carter, Senior Astronomer at the Carter Observatory, the National Observatory of New Zealand.
