Venus is low in the morning skies and is close to the crescent Moon on the 2nd. It is lost in the twilight after this.

Earth is at aphelion on July 5 when it is furthest from the Sun.

 Mars is close to the crescent Moon on the 4th, forming a triangle with Mercury. Mars is also close to Mercury on the 8th.
